No README file = no partial credit for unfinished labs. If you cannot
get your output correct please tell the TAs what you think you have done
correctly and what you think you have not done correctly. You can get
partial credit for implementing a subset of the options correctly:

--- groups properly printed out		      	: 30
--- number of groups properly computed		: 25
--- size of a group containing a square 
	properly computed			: 20

code style:
--- commenting				      	: 10
--- code organization and clarity	      	: 15

potential deductions:
--- solution uses a grid larger than 2 rows:	: -15
--- solution does not use some type of graph    : -20
