Bumpkins.cpp

/*
Programmer: Ben Diegel
Program: Bumpkins of Bumpus
Date: 9/20/17
Notes: I had some trouble with this one. I got the general idea of how to read through the files 
and what i needed to do to get the warrented output. However, I couldnt get my program to fully 
work. I have a bug where my program wont write to file over 6 doorways, plus I couldnt
figure out how to number the doorways correctly without tearing apart all of my code and redoing it.
Also, i know i should have made this program more modular. But Im not too comfertable with
passing by reference with changing data plus having to write to file. Im sure I could have cleaned
up my code by doing so, but atleast i know there is room for improvment for myself.
