               * 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
               *

     * You can then use this within your html template, when you define your grid:
     * <pre>&lt;div ui-grid="gridOptions"&gt;&lt;/div&gt;</pre>
     *
     * To provide default options for all of the grids within your application, use an angular

     * <pre>
     * app.config(function($provide) {
     *   $provide.decorator('GridOptions',function($delegate) {

         *
         * 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
         * getting pointer issues.
         *
         * Alternatively you can directly set the data array:
         *

       *  @ngdoc boolean
       *  @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

     *
     * @description
     * Adapted from debounce function (above)
     * Potential keys for Params Object are:
     *    trailing (bool) - whether to trigger after throttle time ends if called multiple times
     * Updated to use $interval rather than $timeout, as protractor (e2e tests) is able to work with $interval,
     * but not with $timeout
     *
     * Note that when using throttle, you need to use throttle to create a new function upfront, then use the function
     * return from that call each time you need to call throttle.  If you call throttle itself repeatedly, the lastCall
     * variable will get overwritten and the throttling won't work
     *
     * @example
     * <pre>
     * var throttledFunc =  gridUtil.throttle(function() {console.log('throttled');}, 500, {trailing: true});
     * throttledFunc(); //=> logs throttled
     * throttledFunc(); //=> queues attempt to log throttled for ~500ms (since trailing param is truthy)
     * throttledFunc(); //=> updates arguments to keep most-recent request, but does not do anything else.
