+Takes a string and checks to see every openning {,(,[ 
+has a corresponding closing ],),}.
+
+Does this by appending a list of every openning and deletes
+the last element when it comes accross a matching closing.

+If the closing is off a different type or if the list has
+elements remaining then returns False.
