• sum - sums 2 numbers and returns the result.
• capitalize - capitalizes the first letter in a string.
• reverseString - reverses a given string.
• calculator (future) - adds, subtracts, multiplies, or divides two given numbers.
• caesarCipher (future) - Given a string and a 'shift' amount, this function encrypts the given string by 'shifting' each letter in the alphabet by the given shift 'K'.
