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

Include LQD-based solver in Solve
...
A type switch is included to allow for the fact that (*LQ).Solve will
not overwrite the matrix parameter, but if Solve is handed a non-*Dense
matrix, it must be converted.
Solution is confirmed by octave - the test should probably just confirm
that AX == B.

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.

Merge mat64/la into mat64

This has been done to resolve a circular dependency issue that prevents
Norm(2) and Norm(-2) from being implemented.

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.
