* Added AES and AES-CTR modules. AES-CTR conforms to the same counter mode used with AES in *OpenSSL*. * All algorithms now work on Big-Endian architectures. * Now uses CMake for building rather than make files and Visual Studio projects. CMake will generate whatever system is required. * Input function parameters are now marked `const` * File names have been changed to have the prefix `CryptLib_` rather than `Lib`. * Various formatting changes to the files.
