 This module houses the GEOS exceptions, specifically, GEOSException and
 GEOSGeometryIndexError.

    This exception is raised when an invalid index is encountered, and has
    the 'silent_variable_feature' attribute set to true.  This ensures that
    django's templates proceed to use the next lookup type gracefully when
    an Exception is raised.  Fixes ticket #4740.
