-'''
-The 'calc' library contains the 'add2' function that takes 2 values and adds
-them together. If either value is a string (or both of them are) 'add2' ensures
-they are both strings, thereby resulting in a concatenated result.
-NOTE: If a value submitted to the 'add2' function is a float, it must be done so
-in quotes (i.e. as a string).
