Distributed computing.

[JoeyAndres]

Some problem coud benefit from distributed computing. Mixed with sharding, this would be very good.

Boost MPI++ Node cluster

Possible tasks:

• Since sharding use hashing ot know where to store, we can delegate a learning task to a specific machine, thus decreasing bottleneck when learning.
• Can have a master node to delegate problems. Doesn't have to be.
• All these high-level crap coud be written in node, so we really heavily on node wrapping, #9
