ActiveModel::Serializer implementation and Rails hooks

ActiveModelSerializers::Model.attributes

Easily declare instance attributes with setters and getters for each.

All attributes to initialize an instance must have setters.
However, the hash turned by +attributes+ instance method will ALWAYS
be the value of the initial attributes, regardless of what accessors are defined.
The only way to change the change the attributes after initialization is
to mutate the +attributes+ directly.
Accessor methods do NOT mutate the attributes.  (This is a bug).
