Estimated hours taken: 40

 The beginnings of the new bytecode interpreter. Probably
 just over half the code is the same or a
 superficially modified revision of the old one.

bytecode/mb_bytecode.c
bytecode/mb_bytecode.h
	Almost identical. Only real change is made MB_read_cstring not use
	any static variables

bytecode/mb_disasm.c
bytecode/mb_disasm.h
	Again, code very similar. Changed all the functions to write to a
	buffer instead of a file and to allow for bytecode indenting. Output
	format string for some instructions changed (hopefully more menaingful
	than just a dump of numbers)

bytecode/mb_machine.c
bytecode/mb_machine.h
	(completely different from old machine.c)
	The actual part that contains an abstract machine.
	 The rest is really just support code.
	 The instruction_table array is how instructions are dispatched. Look
	 at instr_xxxx for the actual interpreter code. Not all instructions
	 are implemented. MB_step and MB_run execute the actual
	  interpreting code

bytecode/mb_machine_show.h
bytecode/mb_machine_show.c
	  displays output showing the state of the machine


bytecode/mb_mem.c
bytecode/mb_mem.h
	  Identical to old mem apart from file name changes

bytecode/mb_util.c
bytecode/mb_util.h
	  took out strdup (not needed) and changed some comments

bytecode/mb_stack.c
bytecode/mb_stack.h
	  word based stack that will reallocate itself if it needs to


bytecode/mbi.c
	  front end for bytecode interpreter

bytecode/mdis.c
	  disassembles a file and dumps it to the screen
