schedule.txt - the exact same schedule file as the one used for the
               primary input and output

hard.input - one test file for choice 3 and 4

hard.output - the expected output for the hard.input file

     NOTE: for choice 3 in the hard.input file there are two possible
           CORRECT answers - your program should only output one of them
           and would be considered 100% correct for either answer.  The
           "alternate" answer is:

Take A-2 from AAG to AAF
Take A-2 from AAF to AAE
Take A-2 from AAE to AAD
Take A-2 from AAD to AAC
Take C-14 from AAC to ABC
