[EM] pSTV v0.4

[Jeffrey O'Neill]

I've just released version 0.4 of pSTV.   Major updates:
   - my previous implementation of Meek STV was actually Warren STV
     (thanks to David Gamble for pointing this out)
   - both Meek and Warren STV are now correctly implemented
   - the loading and saving of different ballot file formats is clearer
   - more documentation

Methods available are:
   - SNTV
   - IRV
   - Simple STV (description included with the program)
   - ERS97 STV
   - Cambridge, MA STV
   - Meek STV
   - Warren STV
   - highly customizable random transfer STV
   - highly customizable fractional transfer STV

More details and download links are at

Feedback on the program would be appreciated.
