STEP ToyBox: STEP Instance File Diff Tool

This is a tool which reads two Part 21 instance files and the schema file that they conform to and checks to see if the two files are equivalent. Because of the nature of the data, it is not possible to give any kind of diff output. Mostly it just says whether the files are the same or not.
