Some Cody problems ask solvers to remove columns (e.g., CP 7), and others ask solvers to remove rows (e.g., CP 44033). 
Write a function to remove the main diagonal of a square matrix. For example, if the original matrix is
[1  6 11 16 21
 2  7 12 17 22
 3  8 13 18 23
 4  9 14 19 24
 5 10 15 20 25]
the resulting matrix would be
[6 11 16 21
 2 12 17 22
 3  8 18 23
 4  9 14 24
 5 10 15 20]
Elegance encouraged and appreciated.

Chris -- I think the last element in the example result should be 20 rather than 25.

Yes, of course. Thanks.
