destroyTree es6 function

[bharatpatil]

We can import a function to create a tree using es6 module like below:

import { createTree } from 'jquery.fancytree'

It will be helpful if we could also have a destoryTree function to destroy a fancytree instance.
e.g.
import { destroyTree } from 'jquery.fancytree'

Currently, I use following way to destroy a fancytree instance:

const tree = getTree('#' + scope.id);
if (tree.$container) {
tree.$container.fancytree('destroy');
} else {
tree.$div.fancytree('destroy');
}

Also please correct me if this approach of destroying seems fine.

You can use this instead:

tree.widget.destroy();

(With v2.34 I will also add a new method tree.destroy().)
