  #
  # Mince DynamoDb Data Store stores and retrieves data from a DynamoDB table. It supports the same methods
  # as the following libraries:
  #
  # Mince::
  #   A lightweight ruby library to store and retrieve data from MongoDB (https://github.com/asynchrony/mince)
  # HashyDb:: 
  #   A lightweight ruby library to store and retrieve data from a hash in-memory. (https://github.com/asynchrony/hashy_db)
  #
  # Using this library offers more extensibility and growth for your application.  If at any point in time
  # you want to support a different database for all, or even one, of your classes, you only need to implement
  # the few methods defined in this class.
  #
  # You can use the {https://github.com/asynchrony/mince_data_model Mince Data Model} as a helper library to 
  # provide support in writing an application using these data persistance libraries.
  # 
  # To use the Data Store, define your DynamoDB access_key_id and secret_access_key.  If you are using rails
  # you can do this by creating a file at config/aws.yml with the following contents:
  #
  #   development:
  #     access_key_id: REPLACE_WITH_ACCESS_KEY_ID
  #     secret_access_key: REPLACE_WITH_SECRET_ACCESS_KEY
  #    
  # Otherwise, you can set the configurations like so:
  #
  #   require 'aws'
  #
  #   AWS.config.access_key_id = REPLACE_WITH_ACCESS_KEY_ID
  #   AWS.config.secret_access_key = REPLACE_WITH_SECRET_ACCESS_KEY
  #
  # View the aws documentation for more details at http://docs.amazonwebservices.com/AWSRubySDK/latest/frames.html
  #
  # Once you have the settings configured, you can start storing and retrieving data:
  #
  #   data_store = MinceDynamoDb::DataStore.instance
  #   data_store.add 'fruits', id: '1', name: 'Shnawzberry', color: 'redish', quantity: '20'
  #   data_store.get_for_key_with_value 'fruits', :color, 'redish'
