module workflow

[timoxley]

Should require no dependency on node6 for consumption of node6 modules.

Need to figure out a suitable prepublish step.

I'd like to avoid compiling everything to a single file – sifting through es6 transpiled code makes debugging difficult enough already. Sourcemaps perhaps useful, but introduces yet more probably half-baked tooling.

I'm thinking a nice middle ground could be to write out a clone of the module hierarchy, except the files have been precompiled.
