deadlock detection - skeleton for Assignment 4

To compile all code, type:

$ make

To run the resulting code on file test1.txt:

$ ./deadlock < test1.txt

IMPORTANT

Only modify and submit the deadlock_detector.cpp file. Your TAs will supply their own versions of the other files (such as main.cpp) to compile and test your code.
