Comment (by brett):

 Nathann,

 I understand what the code is doing.  When I say "square" I mean "latin
 square"  and in the language of MOLS column 0 of an OA is the row index of
 the Squares, column 1 is the column index and column i is latin square
 i-2.  I am just making the error reporting consistent with the way that a
 MOLS person would interpret it.  Please do not change the branch yet as I
 am in the middle of editing the code.  I was just curious if there was a
 compact way to use a more complex case/switch in cython.  But I think
 there is not so I will just make the changes with nested if statements.
