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)

Subject: Get rid of intostring() and .c_str()
Message-Id: <89ae955518665a61-0-artemis@metatron>

Get rid of the need for intostring() (in addition to tostring()), and having to
place .c_str() after tostring() in rLog calls.

The former is necessary because of some problem with disambiguating which
operator<<(ostream,T) to use when Event is being output, so intostring() calls
T.operator<<(ostream) explicitly. This problem seems to exist only for Events.

It should be possible to solve the latter by returning char* from tostring()
rather than std::string.
