function ultimenu_tree_output in Ultimenu 7

We use tree for future integration with regular dropdown so far.

This is a copy of menu_tree_output() with additional classes added to the output. This is a copy of the amazing menu_block.module with a tweak to hold a region inside data below, and a few other modifications.

Parameters

array $tree: The array data structure representing the tree as from menu_tree_data.

array $config: The array config for the current Ultimenu block.

Return value

string The rendered HTML of that data structure.
