Leeds Code Dojo Strong Pair Programming, Diamond Kata

(Extended/Inspired from Seb Rose's Diamond kata at http://cyber-dojo.org/ )

1. Sparkly Diamonds (New to the code dojo / programming?)

Given a number, print a diamond made up of asterisks (*)

The number passed to your function indicates the number of rows of stars to print until it reaches the widest point of the diamond.

For example:

printDiamond(3);

    *
   * *
  *   *
   * *
    *

printDiamond(4):

     *
    * *
   *   *
