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

Updated meta.yaml gen format; datafetcher and faultchecker tested and both work on Mac and Linux (faultchecker doesn't install pika when installing it for some reason)

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