* 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.
