Subject: Implement ArraySerializer and move old serialization API to a new
 namespace.

The following constants were renamed:

  ActiveModel::Serialization     => ActiveModel::Serializable
  ActiveModel::Serializers::JSON => ActiveModel::Serializable::JSON
  ActiveModel::Serializers::Xml  => ActiveModel::Serializable::XML

The main motivation for such a change is that `ActiveModel::Serializers::JSON`
was not actually a serializer, but a module that when included allows the target to be serializable to JSON.

With such changes, we were able to clean up the namespace to add true serializers as the ArraySerializer.

 module ActiveModel

-  # Provides a basic serialization to a serializable_hash for your object.

-  # A minimal implementation could be:
-  #
-  #   class Person
-  #
-  #     include ActiveModel::Serialization
-  #
-  #     attr_accessor :name
-  #
-  #     def attributes

-  #   person = Person.new
-  #   person.serializable_hash   # => {"name"=>nil}
-  #   person.name = "Bob"
-  #   person.serializable_hash   # => {"name"=>"Bob"}
-  #
-  # You need to declare some sort of attributes hash which contains the attributes
-  # you want to serialize and their current value.
-  #
-  # Most of the time though, you will want to include the JSON or XML
-  # serializations. Both of these modules automatically include the
-  # ActiveModel::Serialization module, so there is no need to explicitly
-  # include it.
-  #

-  #     include ActiveModel::Serializers::Xml

-      #         "created_at": "2006/08/01", "awesome": true}
-      #
-      # This behavior can also be achieved by setting the <tt>:root</tt> option to +false+ as in:
-      #
-      #   user = User.find(1)
-      #   user.as_json(root: false)
-      #   # =>  {"id": 1, "name": "Konata Izumi", "age": 16,
-      #          "created_at": "2006/08/01", "awesome": true}
-      #
-      # The remainder of the examples in this section assume include_root_in_json is set to
-      # <tt>false</tt>.
-      #
-      # Without any +options+, the returned Hash will include all the model's
-      # attributes. For example:
-      #
-      #   user = User.find(1)
-      #   user.as_json
-      #   # => {"id": 1, "name": "Konata Izumi", "age": 16,
-      #         "created_at": "2006/08/01", "awesome": true}
-      #
-      # The <tt>:only</tt> and <tt>:except</tt> options can be used to limit the attributes
-      # included, and work similar to the +attributes+ method. For example:
-      #
-      #   user.as_json(:only => [ :id, :name ])
-      #   # => {"id": 1, "name": "Konata Izumi"}
-      #
-      #   user.as_json(:except => [ :id, :created_at, :age ])
-      #   # => {"name": "Konata Izumi", "awesome": true}
-      #
-      # To include the result of some method calls on the model use <tt>:methods</tt>:
-      #
-      #   user.as_json(:methods => :permalink)
-      #   # => {"id": 1, "name": "Konata Izumi", "age": 16,
-      #         "created_at": "2006/08/01", "awesome": true,
-      #         "permalink": "1-konata-izumi"}
-      #
-      # To include associations use <tt>:include</tt>:
-      #
-      #   user.as_json(:include => :posts)
-      #   # => {"id": 1, "name": "Konata Izumi", "age": 16,

   # Active Model Serializer
+  #
+  # Provides a basic serializer implementation that allows you to easily
+  # control how a given object is going to be serialized. On initialization,
+  # it expects to object as arguments, a resource and a scope. For example,
+  # one may do in a controller:
+  #
+  #     PostSerializer.new(@post, current_user).to_json
+  #
+  # The object to be serialized is the +@post+ and the scope is +current_user+.
+  #
+  # We use the scope to check if a given attribute should be serialized or not.
+  # For example, some attributes maybe only be returned if +current_user+ is the
+  # author of the post:
+  #
+  #     class PostSerializer < ActiveModel::Serializer
+  #       attributes :title, :body
