Thanks to the author of this great plugin: Stephen Harris

* (Events Organiser)[http://wordpress.org/plugins/event-organiser/]
* (Original Shortcode docs)[http://wp-event-organiser.com/documentation/shortcodes/event-list-shortcode/]

This simply extends the Wordpress Events Organiser plugin's shortcode to allow 
the use of an alternative template (in this case shortcode-group-by-date-event-list.php) 
and the use of a new attribute, group_by_period. Pagination is also included 
(add and activate the plugin wp-pagenavi to increase the functionality). 
Don't use the templating ability of the orginal with this as it won't work as 
expected - instead modify the child template.

## Install

* Add the code in extend_eo_events_shortcode.php into your child themes function.php
* shortcode-group-by-date-event-list.php goes in your child theme folder

## Useage

* All attributes of the original [eo_events] shortcode should still 
work (not fully tested)

### New Attribute

* group_by_period
    1. day [default]
    2. month
    3. year

[eo_group_events_by_date event_start_after=now group_by_period=day numberposts=20]
