Release Flowmix 0.2.0

[cjnolet]

This version of Flowmix bumps the version of storm to 0.9.2- giving it the ability to run with Netty instead of ZMQ.

Also- an API package has been established separate from Core. Though things may be moved around a bit more before 1.0.0, the purpose is to allow users to use API without depending on Core- meaning core can change we we need it to but API should remain consistent and go through a deprecation cycle for changes.
