To emphais the tempoary nature we are not storing objects at this time, please see StyleBlackboard for the direction we wish to take this class. API should this interface be included?
Q: Should this class be cloneable? API explain the use of 'keys' and any uniqueness constraints (Set or List?) API X getX(key) ... should this be X get(key) and let the compiler firgure out which one to call based on the signature? API moreover, you might want to consider on 'Objects' and the use of in the API, using generics to avoid multiple get and put methods. API looks alot like a Map ... either document a comparison or add an extends clause? @author Jody Garnett @since 0.7.0
