Centroid.java

* Program: K-Means implementation CS 4315 Assignment 2 Centroid.java
* Programmer: David Torrente (A00652464)
* Date Of Last Edit: 3/01/2016
* Description: This is the centroid class. Note that it contains similar code
*   to the point class and a better OOP implementation would have included
*   abstraction. However, this was not the intent of this program and as
*   such this class was intentionally modular without any additional
*   dependencies. It also includes an additional overloaded constructor
*   for various tests and completely random centroid placement.
