/**
 * Initializes static resources.  The input properties that must be defined are:
 * <ul>
 *   <li>jwnl.configuration : </p>&nbsp; the location of the configuration file for JWNL
 *   <li>edu.cmu.lti.javelin.qa.english.WordNetAnswerTypeMapping.mapFile :
 *   <p>&nbsp; the location of the file specifying a mapping from WordNet synsets
 *   to answer subtypes.  The one-to-many mapping must be specified  
 *   one element per line, with the domain and range values separated by a comma. 
 *   Blank lines and lines beginning with "#" are ignored.  WordNet synsets must be
 *   represented by concatenating the list of lemmas in the synset, separating them 
 *   with a dash ("-"), followed by another "-" and the database file offset of the synset.
 *   (Note: this offset value will vary with the version of WordNet used.)</p>
 *   &nbsp; Thus, an example of an element of the mapping is:</p>
 *     <code>body_of_water-water-8651117,ocean</code>
 * </ul>
 * @throws Exception if one of the required properties is not defined.
