Clearing runtime deprecation notice, requiring virtus ~> 1.0, and bumping version to 0.0.3.

The deprecation notice in particular is thus:

~/discoverer (master*) $ rspec
including Virtus module is deprecated. Use 'include Virtus.model' instead /home/autumn/discoverer/lib/discoverer/model.rb:4:in `include'

Please pull and push the new gem version (0.0.3). I stumbled upon this annoying issue through use of symbolmatrix, so I'd like to see it fixed ASAP.
