/**
 * Entry point for most operations pertaining to REM evidence.

 * Provides various services related to production and consumption of REMEvidence,

 *
 * This class is thread safe, however due to the cost of creating the JAXBContext you should wrap it in a singleton
 * if you intend to create numerous instances.
