This would be in addition to what we currently have in terms of the W class.
The idea is to come up with a separate class that can be used on its own that
does not carry along all the attributes in W. This would allow for exploration
of faster ways to construct the sparse attribute of our W as well as serve as
an interim step to possibly changing the sparse attribute of W with what comes
out of this ticket. It also gives users a choice between the original W and
this new sparse class if they don't need everything in W.
We should always keep W for backwards compatibility. This ticket may
ultimately result in changing the sparse attribute of double in regards to how
it is instantiated.
