/*
 * main.cpp
 * Name: Harry Kran-Annexstein
 *
 * This program sorts numbers provided in a text file, and prints out the sorted
 * number to stdout (the screen).
 * It accepts 2 command-line parameters, the first an integer representing
 * the sort to use.  0 Selection sort, 1 Coctail sort, 2 Gnomesort, 3 Shellsort, 
 * 4 Your Best Sort.
 * The second paremeter is a filename of a file containing the numbers to sort.
 * The file has one integer (could have many digits) per line.
