               * Our basic approach here for event handlers is that we listen for a down event (mousedown or touchstart).
               * Once we have a down event, we need to work out whether we have a click, a drag, or a
               * hold.  A click would sort the grid (if sortable).  A drag would be used by moveable, so
               * we ignore it.  A hold would open the menu.
               *
               * So, on down event, we put in place handlers for move and up events, and a timer.  If the
               * timer expires before we see a move or up, then we have a long press and hence a column menu open.
               * If the up happens before the timer, then we have a click, and we sort if the column is sortable.
               * If a move happens before the timer, then we are doing column move, so we do nothing, the moveable feature
               * will handle it.
               *
               * To deal with touch enabled devices that also have mice, we only create our handlers when
               * we get the down event, and we create the corresponding handlers - if we're touchstart then
               * we get touchmove and touchend, if we're mousedown then we get mousemove and mouseup.
               *
               * We also suppress the click action whilst this is happening - otherwise after the mouseup there
               * will be a click event and that can cause the column menu to close
               *

     * @summary A group of directives that provide a one time bind to a dom element.
     * @description A group of directives that provide a one time bind to a dom element.
     * As one time bindings are not supported in Angular 1.2.* this directive provdes this capability.
     * This is done to reduce the number of watchers on the dom.
     * <br/>
     * <h2>Short Example ({@link ui.grid.directive:uiGridOneBindSrc ui-grid-one-bind-src})</h2>
     * <pre>
          <div ng-init="imageName = 'myImageDir.jpg'">
            <img ui-grid-one-bind-src="imageName"></img>
          </div>
       </pre>
     * Will become:
     * <pre>
         <div ng-init="imageName = 'myImageDir.jpg'">
           <img ui-grid-one-bind-src="imageName" src="myImageDir.jpg"></img>
         </div>
       </pre>
       </br>
       <h2>Short Example ({@link ui.grid.directive:uiGridOneBindText ui-grid-one-bind-text})</h2>
     * <pre>
          <div ng-init="text='Add this text'" ui-grid-one-bind-text="text"></div>
       </pre>
     * Will become:
     * <pre>
     <div ng-init="text='Add this text'" ui-grid-one-bind-text="text">Add this text</div>
       </pre>
       </br>
     * <b>Note:</b> This behavior is slightly different for the {@link ui.grid.directive:uiGridOneBindIdGrid uiGridOneBindIdGrid}
     * and {@link ui.grid.directive:uiGridOneBindAriaLabelledbyGrid uiGridOneBindAriaLabelledbyGrid} directives.

     * @param {array} newRawData Modified set of data
     *
     * This method aims to achieve three things:
     * 1. the resulting rows array is in the same order as the newRawData, we'll call
     * rowsProcessors immediately after to sort the data anyway
     * 2. if we have row hashing available, we try to use the rowHash to find the row
     * 3. no memory leaks - rows that are no longer in newRawData need to be garbage collected
     *
     * The basic logic flow makes use of the newRawData, oldRows and oldHash, and creates
     * the newRows and newHash
     *
     * ```
     * newRawData.forEach newEntity
     *   if (hashing enabled)
     *     check oldHash for newEntity
     *   else
     *     look for old row directly in oldRows

     *     create newRow
     *   append to the newRows and add to newHash
     *   run the processors
     * ```
     * 
     * Rows are identified using the hashKey if configured.  If not configured, then rows
     * are identified using the gridOptions.rowEquality function
     * 
     * This method is useful when trying to select rows immediately after loading data without
     * using a $timeout/$interval, e.g.:
     * 
     *   $scope.gridOptions.data =  someData;
     *   $scope.gridApi.grid.modifyRows($scope.gridOptions.data);
     *   $scope.gridApi.selection.selectRow($scope.gridOptions.data[0]);

         *
         * Most commonly the data is an array of objects, where each object has a number of attributes.
         * Each attribute automatically becomes a column in your grid.  This array could, for example, be sourced from
         * an angularJS $resource query request.  The array can also contain complex objects, refer the binding tutorial
         * for examples of that.
         *
         * The most flexible usage is to set your data on $scope:
         *
         * `$scope.data = data;`

         * This is the most flexible approach as it allows you to replace $scope.data whenever you feel like it without

         * Alternatively you can directly set the data array:

       *  @name updateColumnWidths
       *  @propertyOf  ui.grid.class:GridRenderContainer
       *  @description Determine the appropriate column width of each column across all render containers.
       *
       *  Column width is easy when each column has a specified width.  When columns are variable width (i.e.
       *  have an * or % of the viewport) then we try to calculate so that things fit in.  The problem is that
       *  we have multiple render containers, and we don't want one render container to just take the whole viewport
       *  when it doesn't need to - we want things to balance out across the render containers.
       *
       *  To do this, we use this method to calculate all the renderContainers, recognising that in a given render
       *  cycle it'll get called once per render container, so it needs to return the same values each time.
       *
       *  The constraints on this method are therefore:
       *  - must return the same value when called multiple times, to do this it needs to rely on properties of the
       *    columns, but not properties that change when this is called (so it shouldn't rely on drawnWidth)
       *
       *  The general logic of this method is:
       *  - calculate our total available width
       *  - look at all the columns across all render containers, and work out which have widths and which have
       *    constraints such as % or * or something else
       *  - for those with *, count the total number of * we see and add it onto a running total, add this column to an * array
       *  - for those with a %, allocate the % as a percentage of the viewport, having consideration of min and max
       *  - for those with manual width (in pixels) we set the drawnWidth to the specified width
       *  - we end up with an asterisks array still to process
       *  - we look at our remaining width.  If it's greater than zero, we divide it up among the asterisk columns, then process
       *    them for min and max width constraints
       *  - if it's zero or less, we set the asterisk columns to their minimum widths
       *  - we use parseInt quite a bit, as we try to make all our column widths integers

     * <div class="alert alert-warning" role="alert"><strong>Beta</strong> This feature is ready for testing, but it either hasn't seen a lot of use or has some known bugs.</div>
     *
     * This module provides grouping of rows based on the data in them, similar
     * in concept to excel grouping.  You can group multiple columns, resulting in
     * nested grouping.
     *
     * In concept this feature is similar to sorting + grid footer/aggregation, it
     * sorts the data based on the grouped columns, then creates group rows that
     * reflect a break in the data.  Each of those group rows can have aggregations for
     * the data within that group.
     *
     * This feature leverages treeBase to provide the tree functionality itself,
     * the key thing this feature does therefore is to set treeLevels on the rows
     * and insert the group headers.
     *
     * Design information:
     * -------------------
     *
     * Each column will get new menu items - group by, and aggregate by.  Group by
     * will cause this column to be sorted (if not already), and will move this column
     * to the front of the sorted columns (i.e. grouped columns take precedence over
     * sorted columns).  It will respect the sort order already set if there is one,
     * and it will allow the sorting logic to change that sort order, it just forces
     * the column to the front of the sorting.  You can group by multiple columns, the
     * logic will add this column to the sorting after any already grouped columns.
     *
     * Once a grouping is defined, grouping logic is added to the rowsProcessors.  This
     * will process the rows, identifying a break in the data value, and inserting a grouping row.
     * Grouping rows have specific attributes on them:
     *
     *  - internalRow = true: tells us that this isn't a real row, so we can ignore it
     *    from any processing that it looking at core data rows.  This is used by the core
     *    logic (or will be one day), as it's not grouping specific
     *  - groupHeader = true: tells us this is a groupHeader.  This is used by the grouping logic
     *    to know if this is a groupHeader row or not
     *
     * Since the logic is baked into the rowsProcessors, it should get triggered whenever
     * row order or filtering or anything like that is changed.  In order to avoid the row instantiation
     * time, and to preserve state across invocations, we hold a cache of the rows that we created
     * last time, and we use them again this time if we can.
     *
     * By default rows are collapsed, which means all data rows have their visible property
     * set to false, and only level 0 group rows are set to visible.

     *
     * This module provides the ability to import data into the grid. It
     * uses the column defs to work out which data belongs in which column,
     * and creates entities from a configured class (typically a $resource).
     *
     * If the rowEdit feature is enabled, it also calls save on those newly
     * created objects, and then displays any errors in the imported data.
     *
     * Currently the importer imports only CSV and json files, although provision has been
     * made to process other file formats, and these can be added over time.
     *
     * For json files, the properties within each object in the json must match the column names
     * (to put it another way, the importer doesn't process the json, it just copies the objects
     * within the json into a new instance of the specified object type)
     *
     * For CSV import, the default column identification relies on each column in the
     * header row matching a column.name or column.displayName. Optionally, a column identification
     * callback can be used.  This allows matching using other attributes, which is particularly
     * useful if your application has internationalised column headings (i.e. the headings that
     * the user sees don't match the column names).
     *
     * The importer makes use of the grid menu as the UI for requesting an
     * import.

     * Enables resizing for all columns on the grid. If, for some reason, you want to use the ui-grid-resize-columns directive, but not allow column resizing, you can explicitly set the
     * option to false. This prevents resizing for the entire grid, regardless of individual columnDef options.

     * # ui.grid.treeBase
     *
     * <div class="alert alert-warning" role="alert"><strong>Beta</strong> This feature is ready for testing, but it either hasn't seen a lot of use or has some known bugs.</div>
     *
     * This module provides base tree handling functions that are shared by other features, notably grouping
     * and treeView.  It provides a tree view of the data, with nodes in that
     * tree and leaves.
     *
     * Design information:
     * -------------------
     *
     * The raw data that is provided must come with a $$treeLevel on any non-leaf node.  Grouping will create
     * these on all the group header rows, treeView will expect these to be set in the raw data by the user.
     * TreeBase will run a rowsProcessor that:
     *  - builds `treeBase.tree` out of the provided rows
     *  - permits a recursive sort of the tree
     *  - maintains the expand/collapse state of each node
     *  - provides the expand/collapse all button and the expand/collapse buttons
     *  - maintains the count of children for each node
     *
     * Each row is updated with a link to the tree node that represents it.  Refer {@link ui.grid.treeBase.grid:treeBase.tree tree documentation}
     * for information.
     *
     *  TreeBase adds information to the rows
     *  - treeLevel: if present and > -1 tells us the level (level 0 is the top level)
     *  - treeNode: pointer to the node in the grid.treeBase.tree that refers
     *    to this row, allowing us to manipulate the state
     *
     * Since the logic is baked into the rowsProcessors, it should get triggered whenever
     * row order or filtering or anything like that is changed.  We recall the expanded state
     * across invocations of the rowsProcessors by the reference to the treeNode on the individual
     * rows.  We rebuild the tree itself quite frequently, when we do this we use the saved treeNodes to
     * get the state, but we overwrite the other data in that treeNode.
     *
     * By default rows are collapsed, which means all data rows have their visible property
     * set to false, and only level 0 group rows are set to visible.
     *
     * We rely on the rowsProcessors to do the actual expanding and collapsing, so we set the flags we want into
     * grid.treeBase.tree, then call refresh.  This is because we can't easily change the visible
     * row cache without calling the processors, and once we've built the logic into the rowProcessors we may as
     * well use it all the time.
     *
     * Tree base provides sorting (on non-grouped columns).
     *
     * Sorting works in two passes.  The standard sorting is performed for any columns that are important to building
     * the tree (for example, any grouped columns).  Then after the tree is built, a recursive tree sort is performed
     * for the remaining sort columns (including the original sort) - these columns are sorted within each tree level
     * (so all the level 1 nodes are sorted, then all the level 2 nodes within each level 1 node etc).
     *
     * To achieve this we make use of the `ignoreSort` property on the sort configuration.  The parent feature (treeView or grouping)
     * must provide a rowsProcessor that runs with very low priority (typically in the 60-65 range), and that sets
     * the `ignoreSort`on any sort that it wants to run on the tree.  TreeBase will clear the ignoreSort on all sorts - so it
     * will turn on any sorts that haven't run.  It will then call a recursive sort on the tree.
     *
     * Tree base provides treeAggregation.  It checks the treeAggregation configuration on each column, and aggregates based on
     * the logic provided as it builds the tree. Footer aggregation from the uiGrid core should not be used with treeBase aggregation,
     * since it operates on all visible rows, as opposed to to leaf nodes only. Setting `showColumnFooter: true` will show the
     * treeAggregations in the column footer.  Aggregation information will be collected in the format:
     *
     * ```
     *   {
     *     type: 'count',
     *     value: 4,
     *     label: 'count: ',
     *     rendered: 'count: 4'
     *   }
     * ```
     *
     * A callback is provided to format the value once it is finalised (aka a valueFilter).
     *

     * TreeView uses treeBase for the underlying functionality, and is a very thin wrapper around
     * that logic.  Most of the design information has now moved to treebase.
