Changed implementation of WeightedRips to store simplex values (max distance between simplices' vertices) as an invisible layer on top of each simplex object, so that the data() field of WeightedRips has been freed for use by the users again.

Subject: Intrusive containers for ZigzagPersistence

Use Boost's intrusive containers to store rows in ZigzagPersistence. This
should get rid of the inefficiencies associated with the simplex removal
(through ZigzagPersistence::remove()).
