Ok, shared core looks good, and I added a unit test for Bu::List to check a few

basics.  It works, so now I'm going to apply SharedCore to Bu::List and see how
bad it is.

Also, I got rid of all the warnings and things that showed up during
compilation, they were all silly anyway.

Finally, mkunit.sh is much cooler.  Hard to believe it's a shell script, it now
also adds proper #line directives to the cpp output so if there is an error or
warning g++ will give you the right line number in your .unit file, not the
resultant cpp file.
