Package::Transporter::Rule::Gone - Make a rule ineffective

	use Package::Transporter::Rule;
	$rule->release;

This class changes the public methods of a rule object, so that it's practically ineffective. The ->release method of the standard rule object empties the data of it and changes the class to Package::Transporter::Rule::Gone.

Making a rule ineffective is cheaper than finding and removing it from the tree in Pre_Selection.

Please see the documentation of the upstream package Package::Transporter.
