BIG change.  Started using token field in ui for actions, adding to tag, acitonfactory, database to support the array.  Stored as space separated names
Change Action protocol to require a NSArray be returned from TagIn and TagOut
Adding abstract class to hold common action code
Use [self class] in to reference class methods from within object
Add common code to AbstractAction
Removed magic number in arrayWithCapacity
Removing redundant code from subclasses of AbstractAction
remove getInstance from subclasses; remove NSLogs from previous debugging; correct logic for Timer replacement
