Currently, this is just a hack for ctools plugin styling of menus for twitter bootstrap/radix ui. Menu block support is coming shortly.
Shortly, a 2.x version will be released that uses a plugin system wherein folks can provide different menu styles for custom css or other css frameworks.
A 3.x version will use a custom ctools plugin system to allow exportable and UI-driven configuration of menu style variants. This approach will also be adopted for a d8 version using core's new (slightly) ctools inspired plugin system.
It's very important to note that this module has only been tested with the latest radix git repo. Not making any guarantees!
Credit is due to the zurb-foundation theme folks for their menu utilities which inspired this apparoach. Phptemplate is a nightmare, don't even get me started :P
