 *  included in the default <code>{@value #MAPPINGS}</code> file to see
 *  how this method works.
 *  <p>
 *  This method takes in an object array for the constructor arguments for classes
 *  which have more than two constructors.
 *
 *  @param requestedClass The name of the class you wish to instantiate.
 *  @param initargs The parameters to be passed to the constructor. May be <code>null</code>.
