* an object of actions, or a function that accepts a node and a callback function and calls the callback function with an object of actions available for that node (you can also return the items too).
*
* Each action consists of a key (a unique name) and a value which is an object with the following properties (only label and action are required). Once a menu item is activated the `action` function will be invoked with an object containing the following keys: item - the contextmenu item definition as seen below, reference - the DOM node that was used (the tree node), element - the contextmenu DOM element, position - an object with x/y properties indicating the position of the menu.
*
* * `separator_before` - a boolean indicating if there should be a separator before this item
* * `separator_after` - a boolean indicating if there should be a separator after this item
* * `_disabled` - a boolean indicating if this action should be disabled
* * `label` - a string - the name of the action (could be a function returning a string)
* * `title` - a string - an optional tooltip for the item
* * `action` - a function to be executed if this item is chosen, the function will receive
* * `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
* * `shortcut` - keyCode which will trigger the action if the menu is open (for example `113` for rename, which equals F2)
* * `shortcut_label` - shortcut label (like for example `F2` for rename)
* * `submenu` - an object with the same structure as $.jstree.defaults.contextmenu.items which can be used to create a submenu - each key will be rendered as a separate option in a submenu that will appear once the current item is hovered
