/*
* The aciTree core.
*
* A few words about how item data looks like:
*
* for a leaf node (a node that does not have any children):
*
* {
* id: 'some_file_ID', // should be unique item ID
* label: 'This is a File Item', // the item label (text value)
* inode: false, // FALSE means is a leaf node (can be omitted)
* icon: 'fileIcon', // CSS class name for the icon (if any), can also be an Array ['CSS class name', background-position-x, background-position-y]
* disabled: false, // TRUE means the item is disabled (can be omitted)
* random_prop: 'random 1' // sample user defined property (you can have any number defined)
* }
*
* for a inner node (a node that have at least a children under it):
*
* {
* id: 'some_folder_ID', // should be unique item ID
* label: 'This is a Folder Item', // the item label (text value)
* inode: true, // can also be NULL to find at runtime if its an inode (on load will be transformed in a leaf node if there aren't any children)
* open: false, // if TRUE then the node will be opened when the tree is loaded (can be omitted)
* icon: 'folderIcon', // CSS class name for the icon (if any), can also be an Array ['CSS class name', background-position-x, background-position-y]
* disabled: false, // TRUE means the item is disabled (can be omitted)
* source: 'myDataSource', // the data source name (if any) to read the children from, by default `aciTree.options.ajax` is used
* branch: [ // a list of children
* { ... item data ... },
* { ... item data ... },
* ...
* ],
* random_prop: 'random 2' // sample user defined property (you can have any number defined)
* }
*
* The `branch` array can be empty, in this case the children will be loaded when the node will be opened for the first time.
*
* Please note that the item data should be valid (in the expected format). No checking is done and errors can appear on invalid data.
*
* One note about a item: a item is always the LI element with the class 'aciTreeLi'.
* The children of a node are all added under a UL element with the class 'aciTreeUl'.
*
* Almost all API functions expect only one item. If you need to process more at once then you'll need to loop between all of them yourself.
*
* The `options` parameter for all API methods (when there is one) is a object with the properties (not all are required or used):
*
* {
* uid: string -> operation UID (defaults to `ui`)
* success: function (item, options) -> callback to be called on success (you can access plugin API with `this` keyword inside the callback)
* fail: function (item, options) -> callback to be called on fail (you can access plugin API with `this` keyword inside the callback)
* notify: function (item, options) -> notify callback (internal use for when already in the requested state, will call `success` by default)
* expand: true/false -> propagate on open/toggle
* collapse: true/false -> propagate on close/toggle
* unique: true/false -> should other branches be closed (on open/toggle) ?
* unanimated: true/false -> if it's TRUE then no animations are to be run (used on open/close/toggle)
* itemData: object[item data]/array[item data] -> used when adding/updating items
* }
*
* Note: when using the API methods that support the `options` parameter, you will need to use the success/fail callbacks if you need to do
* any processing after the API call. This because there can be async operations that will complete at a later time and the API methods will
* exit before the job is actually completed. This will happen when items are loaded with AJAX, on animations and other delayed operations (see _queue).
*
