+
+Program Description
+	This is the function that parses the expression. It goes through the expression, and produces a list of 'tokens', where each token represents a part of the expression. For example, '3 + 2' would yield the tokens '3', '+' and '2'. It then returns the list of tokens.
+Assignment Information

+Contributor:    Name, login@purdue [repeat for each]
+    My contributor(s) helped me:
+    [ ] understand the assignment expectations without
+        telling me how they will approach it.
+    [ ] understand different ways to think about a solution
+        without helping me plan my solution.
+    [ ] think through the meaning of a specific error or
+        bug present in my code without looking at my code.
+    Note that if you helped somebody else with their code, you
+    have to list that person as a contributor here as well.
