// mobile dropdown menu state change 
// This code is used for modeling the state of the mobile dropdown menu. 
// When a mobile menu item with a dropdown is touched, the changeMenu function
// is called. It gets all the children of the dropdown and stores them as the
// children variable. During this time, the state of the dropdown menu is saved
// into the currentState array for later. A 'back' item that has an onclick attr
// calling the back() function is appended to the children variable and the
// html of the mobile dropdown is set to the children variable. 
// If the back button is clicked, we get the parent menu of the submenu by popping
// the currentState variable.

var currentState = [];

  var children = $($(e).children()[1]).html();
