Refactored so that transformers can no longer inherit from one another,
but instead all steps are transformers
Made sure we use attr_accessor for instance variables
Locked down rspec to 3.1

The latest as of now
Removed the extra travis gemfiles, now that we don't use activesupport
Renamed reverse to revert
Bumped version to 0.3.0
Merge pull request #1 from iainbeeston/all_transformer_refactor

All transformer refactor
