//	Implementation Summary
//
//	1. Enforce API surface and semantic compatibility with 1.9.x branch
//	2. Improve the module's maintainability by reducing the storage

//	3. Use the same single mechanism to support "private" and "user" data.
//	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
//	5. Avoid exposing implementation details on user objects (eg. expando properties)
//	6. Provide a clear path for implementation upgrade to WeakMap in 2014

	 *
	 * * `max_children` the maximum number of immediate children this node type can have. Do not specify or set to `-1` for unlimited.
	 * * `max_depth` the maximum number of nesting this node type can have. A value of `1` would mean that the node can have children, but no grandchildren. Do not specify or set to `-1` for unlimited.
	 * * `valid_children` an array of node type strings, that nodes of this type can have as children. Do not specify or set to `-1` for no limits.
	 * * `icon` a string - can be a path to an icon or a className, if using an image that is in the current directory use a `./` prefix, otherwise it will be detected as a class. Omit to use the default icon from your theme.
	 * * `li_attr` an object of values which will be used to add HTML attributes on the resulting LI DOM node (merged with the node's own data)
	 * * `a_attr` an object of values which will be used to add HTML attributes on the resulting A DOM node (merged with the node's own data)
	 *
	 * There are two predefined types:
	 *
	 * * `#` represents the root of the tree, for example `max_children` would control the maximum number of root nodes.
	 * * `default` represents the default node - any settings here will be applied to all nodes that do not have a type specified.
