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.

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.
