Consider alternate serialization method

[TheHashTableSlasher]

Currently, data is marshalled via Matlab's undocumented getByteStreamFromArray and getArrayFromByteStream. Although this is the fastest method for pure Matlab clients, other types of clients (i.e. a Python binding) may exist in the future, (and relying on undocumented functions is as stable and future-proof as a box of moldy dynamite) so an open standard would be preferable. Ideally, the server would send a signal to continue using getByteStreamFromArray/getArrayFromByteStream until a non-Matlab client connects, at which point the alternate marshaller is used.

I can't find a suitable method that preserves matrix types, so I'm just going to make one really quickly. If something else pops up that appears suitable, we can use it later.
