Added Code

// Added includes to the stdafc header file.
//  #include <iostream> - Standard IO stream operations
//  #include <iomanip>  - Used for formatting cout e.g setw, left, right
//  #include <string> - To handle strings (not sure if we need it yet,
we do if we add exception handeling)
//  #include <sstream>  - To read the input.txt
// Created shortcuts class for adding coding shortcuts to the code EG
me.p() for system("pause"); and so on
// Created base for PrintMenu() function. Will need to have function
calls added to it as more functions are added to the program.
// Moved PrintMenu into separate class. Can add other menus to this
class. Satisfies one of the 4 file (2 .h 2.cpp) requirements
