Sparse row templates

[Twolvero]

I have implemented SparseRowVectors into the Binary and Unary templates. I have also added an "S" to every result variable that is sparse to keep track of sparse intermediates.

There seem to be still some codegen errors - do you need any help @Frxms ?

As far as i understood it, the Unary class was missing its ROW_VARS case. Could you run the tests again please? @mboehm7
