Update header files to use a more standard name to prevent rereading This is from github report #16. There are likely a few more issues that need to be addressed though this takes care of the major ones.

Introduce shell of vhdlpp program. Create the makefiles and configuration scripts to hold together the vhdlpp front-end program. Create a shell main.

Flesh out VHDL parser engine. Add enough rules to parse a simple VHDL program: Parse library and use clauses, Parse entity declarations, and Parse architecture bodies. Add some parser infrastructure: Handle syntax errors with useful error messages, Include file name and line numbers in parse errors, Add some parser debug aids.
