eventually, take in a --production flag

if true, we will modify the process to be simpler.

the second round of machineJS, run by ensembler, will pick the algorithm with the best score, and just use that, rather than creating dozens and averaging them.

similarly, the original machineJS will only keep the best X many algorithms overall, rather than all of them.

and we'll write everything to a folder so you can load it up again and run it on production servers.
