It is a dict of { post_attr: rel_attr }
If there is a post_attr "thread", the corresponding rel_attr is used
to update the post thread to the correct Post model (in order to
establish a parent-child relation between two models)
When a callable is set as bound value, it will be called to retrieve
the value, as: callable_func(post, related)
Note: bound values can be any value, not only Django field.

* rel_to_post: auto update the post when related object is updated
* thread_model: generated by the metaclass, points to the RelatedPost
model generated for the bindings.thread object.
* field_args: dict of arguments to pass to the ForeignKey constructor,
such as: ForeignKey(related_model, **field_args)
* auto_create: automatically create a RelatedPost for each new item of
the related object and init it with bounded values. Use 'post_save'
signal. If auto_create is callable, use `auto_create(related_object)`.
Be careful with post_to_rel!
* There is no check of permissions when related object is synchronised
from the post, so be careful when enabling post_to_rel.
