docs: getPropertyType
  Utility method which returns the type of value required for the given property.
  URIDestinationCreator uses this method to test if a property is known or not,
  and assumes 'silent' failure if the property is not known.
  
  @param longPropertyName     The long name of the property of interest.
  
  @return Class               The required class for this property's value, or null
  if the property is unknown.
