Core and Vendor code decomposition

Registered by Armando Migliaccio on 2014-11-14

Contributing and reviewing existing and/or new vendor code in Neutron is painful
for a number of reasons. This blueprint is proposing changes to the existing structure
of the project to address these pain points. More precisely changes to the following
areas are being promoted:

Neutron development process
Neutron code structure
Neutron testing
