RegexSD: change ddsim interface to use a dictionary instead of a list
Browse files Browse the repository at this point in the history
Too much hassle to ensure that the list was not duplicating the entries in the list

The original implementation also caused infinite loop by appending to the list that was iterated over causing ddsim to use up all the memory and not do anything

Added a test with an example ddsim steering file
