"The test cases can be no longer edited for this kata".

Btw it was created in the time when there was no separate "initial solution" and "complete solution", many changes was introduced. Obviously some code has been generated from the kata description, which was made when only ruby version existed.

So now the only option is to keep the camel case so I edited only the "initial solution" part.

The default test case contains an undefined function compareMatrices. The assert call already compares for equality.

Hmm, I think the input should be only positive. Will update the description.
