Active Model
==============
Totally experimental library that aims to extract common model mixins from
ActiveRecord for use in ActiveResource (and other similar libraries).
This is in a very rough state (no autotest or spec rake tasks set up yet),
so please excuse the mess.
Here's what I plan to extract:
* ActiveModel::Observing
* ActiveModel::Callbacks
* ActiveModel::Validations
# for ActiveResource params and ActiveRecord options
* ActiveModel::Scoping
# to_json, to_xml, etc
* ActiveModel::Serialization
I'm trying to keep ActiveRecord compatibility where possible, but I'm
annotating the spots where I'm diverging a bit.
