1. create a New->Project->Console application->C(++)->project title = aes (or so)
2. replace the generated main.cpp file with the content of the given aes.cpp file
3. add the aes.h file to the project
4. implement the following functions:
	uint32 SubWord()
	uint32 RotWord()
	void KeyExpansion()
	uint8 xtime()
	void init_xtim()
	uint8 dot()
	void init_state()
	void AddRoundKey()
	void SubBytes()
	void ShiftRows()
	void MixColumns()
5. build the project and run it. at this point it should do the stuff specified in Appendix A and Appendix B of FIPS 197 (that is, create the key schedule for the 128 bit key and use it to encrypt the message from test_appb).
