* An object storing all types as key value pairs, where the key is the type name and the value is an object that could contain following keys (all optional).
*
* * `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.
