Remove unneeded method aliasing of attribute reader: object, with the underscored class name of serializer, to fix issue where a model's attribute name matches that of the underscored prefix of the serializer
Added description of default_serializer_options 

In example it's used to set up root: false for controller
Append an `_id` or `_ids` suffix to associations' keys. Embed objects in root according to their serializers' names.

An `_id` suffix will be appended to the name of HasOne associations, while `_ids` will be appended to the singularized name of HasMany associations. Association keys can still be overridden with the `key` option.

Furthermore, objects embedded in the root are now by default named according to their serializer, instead of the key used for their associations.
use _ids method instead of pluck

Update foreign key naming conventions - fixes #158
Merge pull request #161 from kevins90/fix_attr_name_as_serializer_underscored_prefix

Fix serialization of attribute whose name matches the serializer prefix underscored
Add support for specifying the serializer for an association as a String.

This enables the deferral of the resolution of the serializer class to prevent NameError exceptions due to reference cycles between serializer classes.
Update README.md

Spelling and murkup mistakes fixed.
Update association section on README.md to reflect deprecation of the prefix of the serializer class being used as the accessor to the object we wish to serialize. (reason was previously that the name of the object being serialized is not necessarily going to be the prefix of the serializer class and worse the prefix could have been an attribute of the object itself)
