 TODO: Add generator
 
+This will add an `ApplicationTransForm` model...

+    # app/trans_forms/application_trans_form.rb
+    class ApplicationTransForm < TransForms::FormBase

+
+    class PostForm < ApplicationTransForm

+Note that by having a model with the exact name `ApplicationTransForm`, the generator
+for new Form Models will by default inherit from that model instead of the `TransForm::FormBase`
