Notes/Remarks

calculator works with 2 numbers for now.

caesarCipher works for letters a-z, A-Z, converts it to lowercase, ignores punctuation and numbers.

analyzeArray is divided into helper functions that return values like average, min, max, length. Values from these helper functions are used in the returnedObject method to return an Object and we run our tests against the Object returned by this method. It is assumed that inputArray contains only numbers.

Future Changes/Fixes
