Migrate from AGE 0.3 to AGE 0.2
In the previous version of RubyTL, transformations were enclosed in a Ruby module. You have to remove every ocurrence of "module transformationName - end" to make the transformation work. If you don't do this, a message like this will be raised,
Syntax error. undefined method `rule' for XXX
This means that the DSL definition wasn't loaded properly because of the module definition.
