move dynamic resolution to another module

[jbenet]

talking with @maxogden, decided to move dynamic loading to another module. So it will work like this:

• transformer core + cli
• transformer-resolution module to resolve conversion paths
• transformer-dynamic core api with dynamic string -> module resolution + loading

[jbenet]

Ok this is done. Transformer was broken down into a set of modules, see below. Turns out you can just use any conversions directly. Dynamic resolution is the only thing the main tool/lib does. This means two main workflows emerge:

In your code:

• use transformer cli to install, resolve, and/or compile conversion modules
• include the conversions directly (or your compiled conversions)

In cli / repl:

• use transform cli to convert directly. it does dynamic resolution.
• require('dat-transformer') in repl to convert with dynamic resolution.

Feedback on all this very welcome. I'll close this issue but feel free to comment in this new design here, or open another issue.

transformer submodules

(from the README)

Transformer's core is modular itself. See:

• transformer-type - use it to make a transformer type
• transformer-conversion - use it to make a transformer conversion
• transformer-compose - composes conversions
• transformer-resolve - resolves types into the conversion pipeline between them. (dumb atm)
• transformer-loader - dynamic loading of transformer modules
• transformer-compile - compiles a conversion pipeline into a single module (uses requires).
  • Bundle compiled transformers with browserify
• transformer (this module) - all core as one library, and two command line tools:
  • transformer - utility to install, resolve, and compile transformer modules
  • transform <types> < <infile> > <outfile> - expose any transformer as a pipe-loving unix utility

For making your own types and conversions:

• transformer-pkg - cli tool to make, test, publish types + conversions in under one minute (ACT NOW!!!)
• transformer-test - tests your types + conversions (used by transformer-pkg)

• transformer-website - the website: http://transform.datadex.io
