Erik Johnston	bbfe4e996c	Make get_state_groups_from_groups faster. ... Most of the time was spent copying a dict to filter out sentinel values that indicated that keys did not exist in the dict. The sentinel values were added to ensure that we cached the non-existence of keys. By updating DictionaryCache to keep track of which keys were known to not exist itself we can remove a dictionary copy.	2017-05-17 15:12:15 +01:00
