# This is the generic generator class. Right now, it really only covers
# containing the different pieces (blueprint builder, testscript builder) in
# one place, as well as outputting and storing. A lot of this code is repeated
# from the testscript_generator.rb file, which should be the case until the
# generator that is currently baked into that file (interaction conformance) is
# extracted into its own class.
