/*

 * Create a callback list using the following parameters:

 *	options: an optional list of space-separated options that will change how

 *			the callback list behaves or a more traditional option object

 *

 * By default a callback list will act like an event callback list and can be

 * "fired" multiple times.

 *

 * Possible options:

 *

 *	once:			will ensure the callback list can only be fired once (like a Deferred)

 *

 *	memory:			will keep track of previous values and will call any callback added

 *					after the list has been fired right away with the latest "memorized"

 *					values (like a Deferred)

 *

 *	unique:			will ensure a callback can only be added once (no duplicate in the list)

 *

 *	stopOnFalse:	interrupt callings when a callback returns false

 *
