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
