Turned into Eclipse project.
Added google test to project.
Added a hex converter, to convert normal strings to their hex encoding
and reverse.
Tests pass.
Updated HexConverter with alternative function using C functions.
Added new HexConverter tests.
First try for AES (CBC) encryption and decryption.
Does not work yet. (Most likely because of the use of std::string!)
CBC now works.
But test still fails (porbably because no padding was used!)
Added AES (CTR).
