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 <boost/iterator/indirect_iterator.hpp>
#include <boost/python.hpp>

boost::indirect_iterator<dp::VChain::const_iterator> chain_begin(dp::VChain& c) { return boost::make_indirect_iterator(c.begin()); }
boost::indirect_iterator<dp::VChain::const_iterator> chain_end(dp::VChain& c) { return boost::make_indirect_iterator(c.end()); }
void export_chain()
{
bp::class_<dp::VChain>("Chain")
.def("__iter__", bp::range<bp::return_internal_reference<1> >(&chain_begin, &chain_end))
.def("__len__", &dp::VChain::size)
