Removed the points iterator in PersistenceDaigram; replaced it with a __iter__ method.
Got rid of some python code in __init__.py, since it was not needed with the above change.
Changed the docs to reflect this.
#include <utilities/log.h>

static rlog::RLogChannel* rlFiltration = DEF_CHANNEL("topology/filtration/info", rlog::Log_Debug);
static rlog::RLogChannel* rlFiltrationDebug = DEF_CHANNEL("topology/filtration/debug", rlog::Log_Debug);
