Moved recipes, tools, pkgs, and metadata dirs from data/ to data/build/ for a cleaner root dir. Adjusted code to correct for this change.

 - Make communication between parse_setup and setup_to_meta JSON
 - Refactor generate_metadata() into class
 - Filter out numpy, because it is implied by Conda

Added comments on everything relevant; refactored setup_to_meta.py; modified how parse_setup is called from setup_to_meta

Implemented parsing of setup.py files within a buildout recipe; next is to generate meta.yaml files for each setup file parsed
