def get_member(self, name):
assert self.is_collection<EOL>return self.provider.get_resource_inst(<EOL>util.join_uri(self.path, name), self.environ<EOL>)<EOL>
Return child resource with a given name (None, if not found).

        This method COULD be overridden by a derived class, for performance
        reasons.
        This default implementation calls self.provider.get_resource_inst().
