Add Reset method
...
Reset allows reuse of used matrices, a use that would otherwise be
blocked by dim checking for many operations.

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.

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.

Change NewDense signature and behaviour
...
This is an API breaking change.
NewDense now panics if len(mat) != r*c, unless mat == nil. When mat is
nil a new, correctly sized slice is allocated.

Add test for Norm
...
Norm(±2) is, not surprisingly, difficult to pin down. The expected
values here agree with numpy well for Norm(2), less will with MATLAB
and the expectation for Norm(-2) is a fair amount (FWIW at this
magnitude) away from the numpy and MATLAB values which agree quite
well with each other.

Forbid loading column major blas matrix

This may change. Perhaps we can have an allocating LoadBlas for column
major blas matrices. Thinking.

Allow callers to know number of elements copied

Copy does not fail and (reflecting the built in) copies the minimum
range of the source and destination. Return the number of rows and
columns copied so the caller can determine whether to fail.
