/**
 * William Smolinski
 * CISS 241
 * Assignment 2-11: The program takes an input file that contains objects of the yankees class and gathers the fields
 * from the input yankees file classes and outputs them in plain text one character at a time to an output file. The program
 * has one main try-catch block that handles exceptions that will end the program. Within the block is the while loop that will loop
 * through the input file gathering each object, one at a time, and getting the fields from that object to then write to the output file.
