Debugged ZigzagPersistence (having added heavier consistency checking)
* Added DEBUG_CONTAINERS option (uses std::__debug::* containers for chains
and in ZigzagPersistence)
* Added SizeStorage specialization for std::deque<T>
* ZigzagPersistence got a lot more consistency checking (in debug mode only,
which now crawls); as a result it's been debugged (running on non-trivial examples)
* examples/rips/rips-zigzag takes command-line options
* added ChainWrapper::clear()
* added Simplex::VertexDimensionComparison
* added PairwiseDistances class (for computing distances between points in a
container according to a distance functor)
