// Utility function that handles the manipulation of class names in the UI
// generally responding to user events (e.g. mouseovers/mouseouts/etc.). Supports:
//  1. swap - swaps one class for another
//  2. add - adds a class (if it's not already there)
//  3. remove - removes a class (if it is there)
//  4. check - checks if a class exists on the element
//  5. swapAdd - if c1 exists, swap c2 in its place, else
//               add c2.
