Function to print a diamond shape

[Jay Norwood]

A problem with the previous brad measurement is that his solution 
creates a diamond of size 2n+1 for an input of n.  Correcting the 
size input for brad's function call, and re-running, I get this.  
So the various solutions can have overhead computation time of 
40x difference, depending on the implementation.
