Review of Grid Chapter 11 (10-Grid.pier)

No. This is correct.  #new is used only the first time, naively, and fails since only the default 3x3 grid is populated regardless of the size set after #new is called.   #basicNew is used instead so that the grid size can be set before #initialize is called.  This echos the original tutorial we are porting to Pharo 3 http://squeak.preeminent.org/tut2007/html/034.html.
