# Small helper class. Instanciate with
# transform = CFMapTransformer(key)
# or
# transform = CFMapTransformer(key, map)
# default map value is to use The map of current event.
#
# The key is used to keep track of transform. Different transforms
# on same map should use different key to prevent mixup
# transformAll(criteria,whatTo)
# criteria can be a single String or a list,
# whatTo can be a single String or a list.
# This will scan the whole map for item's whose
# "name" are in the list of criteria and transform
# the to one of the whatTo objects, choosen randomly.
# original object is kept in inventory of newly created
# item and can be restored from there
# untransformAll()
# this no argument method cancel all changes that have been
# made by transformAll
