Detailed Description
Base class for unimplemented instructions that cause a warning to be printed (but do not terminate simulation).
This implementation is a little screwy in that it will print a warning for each instance of a particular unimplemented machine instruction, not just for each unimplemented opcode. Should probably make the 'warned' flag a static member of the derived class.
