A preferential ballot filling UI in Javascript and PHP.

Upd. 2005-03-30: cleaned up the code, made it a class and added a very useful function: Expand_Parties().

This is a preferential ballot filling user interface, mainly useful for Condorset methods, written in Javascript and server-side PHP. It was originally developed for the LFW project and is unfortunately not very well documented. The filler is designed for large elections -- for smaller ones, say, max. 5 candidates, it is definitely an overkill.
