USAGE
  form <model-class> <view-name> [scenario]

DESCRIPTION
  This command generates a form view that can be used to collect inputs
  for the specified model.

PARAMETERS
 * model-class: required, model class. This can be either the name of
   the model class (e.g. 'ContactForm') or the path alias of the model
   class file (e.g. 'application.models.ContactForm'). The former can
   be used only if the class can be autoloaded.

 * view-name: required, the name of the view to be generated. This should
   be the path alias of the view script (e.g. 'application.views.site.contact').

 * scenario: optional, the name of the scenario in which the model is used
   (e.g. 'update', 'login'). This determines which model attributes the
   generated form view will be used to collect user inputs for. If this
   is not provided, the scenario will be assumed to be '' (empty string).

EXAMPLES
 * Generates the view script for the 'ContactForm' model:
        form ContactForm application.views.site.contact
