61aa81a28f Reduce cost of row operations in QR 
It is not obvious how to get similar optimisations into the Q'B
operation without allocation, so I'm leaving that.

308e631af1 Add views on rows 
This was suggested in PR Issue#6. Here it is used to simplify
Vectorer-based operations. The next commit will use it in place of
Row/SetRow pairs in decomposition functions.

80e9574c40 Allow Rank and Cond to work without U or V 
Previously we obtained the dimension of A from U and V rather than just
keeping them internally. This prevented Rank and Cond being used if
those matrices were not requested.

23d9ba91cb Complete fix for issue #5 
This updates the comments describing SVD behaviour and ensures that the
correct matrices are constructed.

Output disagrees with R's svd function in sign only.

b0e0bdf3de Rename BlasMatrix to RawMatrix 
The argument is that people don't care about the underlying
representation. I think they should, but this doesn't really prevent
them from doing so.
