Added class names sorting (statistics)

from vote.models import Participation

from voters.models import Voter, Group

import re

def live_results(request, election_id):

    context = admin.site.each_context(request)

            'percentage': round((voted / total * 100), 2) if total > 0 else 0

        })

    def sort_key(item):

        name = item.get('class_name') or ""

        match = re.search(r'd+', name)

        num = int(match.group()) if match else 0

        return (num, name.lower())

    stats_by_class.sort(key=sort_key)

    remote_count = Participation.objects.filter(election=election, is_remote=True).count()

    stationary_count = total_participated - remote_count;
