  	 * ItemManager is used to seamlessly convert between string that come from the user input to whatever

  	 * another operate with items, such as Tags, Filter, Autocomplete and Suggestions. Default implementation 
  	 * works with `String` type. 
  	 *
  	 * Each instance of `TextExt` creates a new instance of default implementation of `ItemManager`
  	 * unless `itemManager` option was set to another implementation.
  	 *
  	 * To satisfy requirements of managing items of type other than a `String`, different implementation
  	 * if `ItemManager` should be supplied.
  	 *
  	 * If you wish to bring your own implementation, you need to create a new class and implement all the 
  	 * methods that `ItemManager` has. After, you need to supply your pass via the `itemManager` option during
  	 * initialization like so:
  	 *
  	 *     $('#input').textext({
  	 *         itemManager : CustomItemManager
  	 *     })

  	 * TextExtPlugin is a base class for all plugins. It provides common methods which are reused

  	 * All plugins must register themselves by calling the `$.fn.textext.addPlugin(name, constructor)`
  	 * function while providing plugin name and constructor. The plugin name is the same name that user
  	 * will identify the plugin in the `plugins` option when initializing TextExt component and constructor
  	 * function will create a new instance of the plugin. *Without registering, the core won't
  	 * be able to see the plugin.*
  	 *
  	 * <span class="new label version">new in 1.2.0</span> You can get instance of each plugin from the core

  		/**
  		 * TextExt provides a way to pass in the options to configure the core as well as
  		 * each plugin that is being currently used. The jQuery exposed plugin `$().textext()` 
  		 * function takes a hash object with key/value set of options. For example:
  		 *
  		 *     $('textarea').textext({
  		 *         enabled: true
  		 *     })
  		 *
  		 * There are multiple ways of passing in the options:
  		 *
  		 * 1. Options could be nested multiple levels deep and accessed using all lowercased, dot
  		 * separated style, eg `foo.bar.world`. The manual is using this style for clarity and
  		 * consistency. For example:
  		 *
  		 *        {
  		 *            item: {
  		 *                manager: ...
  		 *            },
  		 *
  		 *            html: {
  		 *                wrap: ...
  		 *            },
  		 *
  		 *            autocomplete: {
  		 *                enabled: ...,
  		 *                dropdown: {
  		 *                   position: ...
  		 *                }
  		 *            }
  		 *        }
  		 *
  		 * 2. Options could be specified using camel cased names in a flat key/value fashion like so:
  		 *
  		 *        {
  		 *            itemManager: ...,
  		 *            htmlWrap: ...,
  		 *            autocompleteEnabled: ...,
  		 *            autocompleteDropdownPosition: ...
  		 *        }
  		 *
  		 * 3. Finally, options could be specified in mixed style. It's important to understand that
  		 * for each dot separated name, its alternative in camel case is also checked for, eg for 
  		 * `foo.bar.world` it's alternatives could be `fooBarWorld`, `foo.barWorld` or `fooBar.world`, 
  		 * which translates to `{ foo: { bar: { world: ... } } }`, `{ fooBarWorld: ... }`, 
  		 * `{ foo : { barWorld : ... } }` or `{ fooBar: { world: ... } }` respectively. For example:
  		 *
  		 *        {
  		 *            itemManager : ...,
  		 *            htmlWrap: ...,
  		 *            autocomplete: {
  		 *                enabled: ...,
  		 *                dropdownPosition: ...
  		 *            }
  		 *        }
  		 *
  		 * Mixed case is used through out the code, wherever it seems appropriate. However in the code, all option
  		 * names are specified in the dot notation because it works both ways where as camel case is not
  		 * being converted to its alternative dot notation.

  		 * TextExt allows for overriding of virtually any method that the core or any of its plugins
  		 * use. This could be accomplished through the use of the `ext` option.
  		 *
  		 * It's possible to specifically target the core or any plugin, as well as overwrite all the
  		 * desired methods everywhere.
  		 *
  		 * 1. Targeting the core:
  		 *
  		 *        ext: {
  		 *            core: {
  		 *                trigger: function()
  		 *                {
  		 *                    console.log('TextExt.trigger', arguments);
  		 *                    $.fn.textext.TextExt.prototype.trigger.apply(this, arguments);
  		 *                }
  		 *            }
  		 *        }
  		 *
  		 * 2. Targeting individual plugins:
  		 *
  		 *        ext: {
  		 *            tags: {
  		 *                addTags: function(tags)
  		 *                {
  		 *                    console.log('TextExtTags.addTags', tags);
  		 *                    $.fn.textext.TextExtTags.prototype.addTags.apply(this, arguments);
  		 *                }
  		 *            }
  		 *        }
  		 *
  		 * 3. Targeting `ItemManager` instance:
  		 *
  		 *        ext: {
  		 *            itemManager: {
  		 *                stringToItem: function(str)
  		 *                {
  		 *                    console.log('ItemManager.stringToItem', str);
  		 *                    return $.fn.textext.ItemManager.prototype.stringToItem.apply(this, arguments);
  		 *                }
  		 *            }
  		 *        }
  		 *
  		 * 4. And finally, in edge cases you can extend everything at once:
  		 *
  		 *        ext: {
  		 *            '*': {
  		 *                fooBar: function() {}

  		 *
  		 * All plugins that wish to affect how the data is presented or sent must react to 
  		 * `getFormData` and populate the data in the following format:

  		 *     {
