This plugin displays an alphabetical index of all entries. It uses these
optional config variables from config.py, shown here with their defaults:
 
py['index_trigger']            = '/site-index'
py['index_num_columns']        = 2
py['index_letters_first']      = True
py['index_title']              = 'index'
py['index_use_story_template'] = True

- use a template instead of hard-coded HTML
