# Proof of concept to create a class from a string instead of writing it to a
# file and then loading it.
#
# I hope to use this to create doubles in the future, though it will make
# debugging the generated code a little  harder, it always bothered me that I
# was writing and reading files.  It's slower and wastes cycles on the HD.
# Probably shouldn't bother me that much, but it does..
