RE: [FR-devel] RE: Databus hash problem **URGENT**

[Rich Kilmer]

Done...passes unit tests!

Changes all 'hash' behavior to 'map':

#slot.put(key, value)
#slot.get(key) #=> value
#slot.remove(key)
#slot.clear #=> removes all items from map, queue, stack 

The methods above remain the same...these change:

#slot.is_map_slot? #slot.map #=> turn slot into map slot and return Map

Extra method on Map

myHash = {1=>"me", 2=>"you}
slot.map.map=myHash

So you can set up a map quickly
