Added LFSR matching v1:
- Added functions to check whether LFSR and returned states match (it's not complete).
Changes in Traverse and execute CRC function v7:
- Pass correct tree to do_mem_ref function
Changes in Sym_exec v8:
- Added get_first_value () function in state class to get state's first value.
