Description

The setting pruneLeafyBranches on RecursivePrefixTreeStrategy depends on abstract class LegacyCell and therefore trees like the newly added S2PrefixTree cannot benefit for such optimization.

It is proposed to add a new specialize interface for cell interface and make the setting depends on it instead of LegacyCell.
