Intermediate commit while converting to the new architecture * Converted Filtration into StaticPersistence and DynamicPersistenceTrails (both right now work with the underlying std::vector rather than std::list order) * Filtration is now just an auxilliary glue (a map between Complex and Persistence) * Whether chains are vectors or lists can be interchanged * Added PersistenceDiagram with a simple bottleneck_distance() function * Converted triangle, alphashapes3d, and cech-complex examples * Lots of organizational changes (factoring utilities out into containers.h, indirect.h, property-maps.h) * Trying to document along the way with NaturalDocs-type comments

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.
