gemified and added a Railtie, fixed tests, and removed old {read,write}_inheritable_attribute style of accessors
fix gemspec name of repo (still have a underscore/hyphen schism)
trying to follow rails 3.2.2 plugin gems conventions more
load the files manually since this isn't in vendor/plugins anymore
ditch railtie for now, and ensure ActiveRecord::Base.semantic_attributes() reader defaults to a set if nil
add ruby 1.9.* support to semantic_attributes
ruby 1.9.*: instance_methods returns symbols now, so use method_defined? instead
