#entity_class_for_obj(object, options) ⇒ Class
Attempt to locate the Entity class for a given object, if not given
explicitly. This is done by looking for the presence of Klass::Entity,
where Klass is the class of the object
parameter, or one of its
ancestors.

#present(*args) ⇒ Object
Allows you to make use of Grape Entities by setting
the response body to the serializable hash of the
entity provided in the :with
option. This has the
added benefit of automatically passing along environment
and version information to the serialization, making it
very easy to do conditional exposures. See Entity docs
for more info.
