//  Purpose
//  This program will be implementing a console, command line based Multimedia 
//  Organizer.   The basic idea is that your current Video, CD, DVD, cassette, etc 
//  collection should be able to be organized along with other students' collections 
//  so that we have a huge database of multimedia items that can be borrowed, 
//  traded, etc.(program spec)
//
//  the output files shows if the commands were successful or not, also print out
//  informations stored in the array
//

/*
On my honor:

- I have not discussed the C++ language code in my program with anyone other than my 
  instructor or the teaching assistants assigned to this course.

- I have not used C++ language code obtained from another student, or any other 
  unauthorized source, either modified or unmodified. 

- If any C++ language code or documentation used in my program was obtained from another 
  source, such as a textbook or course notes, that has been clearly noted with a proper 
  citation in the comments of my program.

- I have not designed this program in such a way as to defeat or interfere with the normal 
  operation of the Curator System.
