DecoLite is a little gem that allows you to use the provided DecoLite::Model class to dynamically create Decorator class objects. Use the DecoLite::Model class directly, or inherit from the DecoLite::Model class to create your own unique subclasses with custom functionality. DecoLite::Model includes ActiveModel::Model, so validation can be applied using ActiveModel validation helpers (https://api.rubyonrails.org/v6.1.3/classes/ActiveModel/Validations/HelperMethods.html) you're familiar with; or, you can roll your own - just like any other ActiveModel. DecoLite::Model allows you to consume a Ruby Hash that you supply via the initializer (DecoLite::Model#new) or via the DecoLite::Model#load! method. Any number of Ruby Hashes can be consumed. Your supplied Ruby Hashes are used to create attr_accessor attributes (or "fields") on the model. Each attribute created is then assigned the value from the Hash that was loaded. Again, any number of hashes can be consumed using the DecoLite::Model#load! method.

ActiveModel validation against duplicating records.

ActiveRecord dirty tracking that compares every attribute to it's value before type cast and marks all changes detected as changed attributes. This makes it possible to detect `user.name.upcase!` `user.roles << 'some_role'` and similar implicit changes. To make it automatic on `save`, this module sets up a `before_validation` callback when included into a model.
