Update of /cvsroot/avida/avida/current/source/cpu
In directory usw-pr-cvs1:/tmp/cvs-serv25711/source/cpu

Modified Files:
	Makefile.am hardware_base.cc hardware_base.hh hardware_cpu.cc 
	hardware_cpu.hh hardware_factory.cc hardware_factory.hh 
	head.cc label.cc label.hh 
Log Message:
Some more setup to implement new CPU types (nothing too drastic or important):
 * added files hardware_4stack.{cc,hh}
 * Setup the instruction library as a requirement to be passed into the
   hardware right at its creation, rather than be set later.
 * Added a bunch of asserts all over for debugging.
 * Added OK() methods to several classes for debugging.
