[nicm2]

• Finish rpnToResult for Calculator
• Add unbalanced parenthesis check and in original FRQ, or other error checks. FYI, usually when structuring code with error checking it can greatly impact code structure.
• Build in Power of operator ^:2 ^ 1 = 2, 2 ^ 2 = 4, 2 ^ 3 = 83.
• Build an API to receive an expression and respond with a result. This is a good opportunity to respond with an error if you built in parenthesis or other error checking
