Impulse v0.0.2

Impulsev0.0.2 implements "Impulse Manifests" and features a complete rewrite of the task pipeline to aid in modularity.

Impulse Manifests

Impulse manifests are supersets of the Fireworks Workflow Configuration files. Essentially, Impulse is a work flow configuration schema with a controlled vocabulary. Right now, that vocabulary exists only in my head and in the code. It needs to be documented.

Task Pipeline Rewrite

I done goofed and tried to go all functional but I now see that was a bad idea. It is better for readability to use the class-based system, particularly interacting with Impulse manifests.

This is a test release. I am hoping that we can use this to automatically version Impulse implementations on remote clusters vs clients.
