// Required Files:
//   AttribProgram.cpp, AttribLib.dll, AttribDef.dll
//
// To Build:
//   - For compilation AttribDef.dll and AttribLib.dll need to be 
//     in the AttribProgram project folder.
//   - For running AttribDef.dll and AttribLib.dll need to be in 
//     the AttribProgram Project debug folder.
//   - compile and run.
