Summary: Added Input File CMD Line Argument

Details: Specifiying output was such a good idea, I implemented it for the input file as well. This takes care of the caveat of having to specify the "-h" option without providing an input file. If the "-h" parameter is passed at all, the program will print usage and exit.
