'''
A Narcissistic Number is a number which is the sum of its own digits,
 each raised to the power of the number of digits in a given base.
 In this Kata, we will restrict ourselves to decimal (base 10).

For example, take 153 (3 digits):

    1^3 + 5^3 + 3^3 = 1 + 125 + 27 = 153

and 1634 (4 digits):

    1^4 + 6^4 + 3^4 + 4^4 = 1 + 1296 + 81 + 256 = 1634

The Challenge:

Your code must return true or false depending upon whether the given
 number is a Narcissistic number in base 10.

Error checking for text strings or other invalid inputs is not required,
 only valid integers will be passed into the function.
