	Project 2
	Student Name: Connor Taffe
	Student UALR ID (last four digits): XXXX
	Project Description:
		This project takes input from stdin and lexes it into a thread-safe queue,
		items are popped off the queue by the parser, and lexed into a tree.
		The tree is then recursively evaluated by the parser and the result is
		displayed.
	Project Due Date: 9/9/2014
