////////////////// Navigation ////////////////////
//// Overview: A responsive, collapsing, mobile menu enabled, drop down menu system
//
// * Applies functions to ul.navigation elements on the page
// * Collapses menu items into a "more" menu
//// Dependencies
//
// Must define mobile width stop point, originally defined in my page_structure.scss
// - Depends on navigation.scss: the whole concept is dependent on a right aligned navigation
// -- For left aligned, you must switch to a <total child widths>:<parent width> comparison technique
// -- I assume this takes more processing time, so I opted for position
// - Must define customization options for each menu, using mixin provided in the navigation.scss
//// Functions: details on each function are inline as the function progresses
//
// Add elements to navigation
// --> function addNavigationElements( selectedNav )
//
// Collapse the navigation into a "more" menu
// --> function collapseNavigationElements( selectedNav )
//
// Add actions to the navigation elements
// --> function addNavigationActions( selectedNav )
//
// Make sure that dropdowns don't fall off the screen
// --> function theDropSide( selectedNav )
//////////////// End Navigation ////////////////////
// Determine the best side for the drop down menus to open on
