Updated the docstrings for GHOP access methods. The checkRoleAndStatusForTask and checkStatusForTask methods' docstrings tell more on what they specifically do and why they both exist separately.

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

class GEOSException(Exception):

    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.
