#CFItemBroker.py
#An often used bit of code to add or remove a number of objects
#Useful for removing items (like in payment or as part of
#an inventory check)  This is also useful for setting the number
#of a newly created item(s) as it will check for existing item(s) and add
#the appropriate number of new items avoiding such silliness as the
#number of the existing items being reset.
#This will not check for the existence of an item as that would better
#be done in the calling script so you can be flexible.
