/**
 * BRPTools.clickableMenus
 * Handles menus that opens on click (fake dropdown)
 * Each call registers an object into "instances" array
 * so we can handle closing other menus while opening one.
 * When javascript is disabled, the menus are still showing 
 * using CSS hover
 * @param target		represents the element where the Click is binded. 
 * 						the Click event closes all children of @target with 
 * 						.show-on-click classname
 * @param otherToggles 	Array of jQuery selectors which targets elements to toggle,
 * 						other than children of target that uses .show-on-click
 *
 * Css to add to your css file
    .show-on-hover,
    .show-on-click{
	    display:none;
    }
    *:hover > .show-on-hover,
    *:hover > .show-on-click{
	    display:block;
    }
 
 * Css to add to css file loaded by javascript (often call InitialState.css or Script-Enabled.css)
 
    *:hover > .show-on-click{
        display:none;
    }
    
 * Usage Example                      Menu To Open      Other element to toggle
 *   BRPTools.clickableMenus.register("#BRP-Products", $('#menu-overlay'));
 *
