 * Enhancement Structure (RedLink's analysis service response) Parser API. The Enhancement Structure (https://stanbol.apache.org/docs/trunk/components/enhancer/enhancementstructure)
 * can be serialized in different formats, being RDF the default one. Each implementation of the parser has the mission to read the structure in the incoming format and transform it
 * in a {@link Enhancements} object, allowing the user to use the results in an easier way.
