/*
Shawn O'Neil - Emulating Diamond inheritance in C

Golly Gee Gosh I've got to be close. I'm fairly sure I've got it this
time, I don't think I need to follow two pointers in any XtoX data
copy methods, as well as in the Genius2MathMajor data copy for just
the Discipline stuff, at least I really hope not.
