Do we need Mat, Vec, TMmat, Diag, Sym and other matrix types?

In my head I had been thinking that the Mat type you want to 
introduce would be just an alias to a 2-dimensional Slice with a 
particular SliceKind and iterator. Am I right on that?

If that's the case, why not introduce a Tensor type that 
corresponds to Slice but in column-major storage and then have 
Mat (or Matrix) be an alias to 2-dimensional Tensor with a 
particular SliceKind and iterator.
