 * ApplicationDataResponse provides a standard response object for use by application
 * data providers. 
 * 
 * The ApplicationDataResponse works off of the idea that the KEY=>VALUE paradigm
 * is more or less universal and suits (or is at least compatible with) a broad array
 * of data sources. By guaranteeing that all data providers will return objects of this type
 * in response to data requests, it is possible to simplify the process of integrating
 * and assimilating data from multiple heterogeneous sources
