Get views and manipulate them (form validation...)

In a similar way of the OERSted library (http://pypi.python.org/pypi/oersted/1.2.0), be able to generate an object representing a view (like a form) which will features :
- fill the form with default values,
- set values in fields and perform 'onchange' functions on the fly,
- form validation,
- navigate from a view to another through relation fields.
