Detailed Description

Your implementation of the functions defined in symbol.h. You may add other functions if you find it helpful. Added functions should be declared static to indicate they are only used within this file. The reference implementation added approximately 90 lines of code to this file. This count includes lines containing only a single closing bracket (}).
