 Radix sort is a sorting algorithm that takes as input an array of integers and uses a sorting subroutine( that is often another efficient sorting algorith) to sort the integers by their radix, or rather their digit.  Counting Sort, and Bucket Sort are often times used as the subroutine for Radix Sort.

 * Input Array: [170, 45, 75, 90, 802, 24, 2, 66]
 * Output Array (Sorted):  [2, 24, 45, 66, 75, 90, 170, 802]

+### Step 1:
 The first step in this algorithm is to define the digit or rather the "base" or radix that we will use to sort.
 For this example we will let radix = 10, since the integers we are working with in the example are of base 10.

+### Step 2:
 The next step is to simply iterate n times (where n is the number of digits in the largest integer in the input array), and upon each iteration perform a sorting subroutine on the current digit in question.
