 34  * Main Theater for WordPress class.
 35  *
 36  * With the Theater for WordPress plugin it is possible to manage and publish _events_ that have one of more _dates_.
 37  *
 38  * So if you run a theater then 'The Sound Of Music' is an event and the show this weekend is a date.
 39  *
 40  * ## Getting started
 41  *
 42  * ### Events
 43  * <code>
 44  * // Retrieve a list of all events.
 45  * $events = new Theater_Event_List;
 46  * foreach ( $events() as $event ) {
 47  *      // $event is a Theater_Event object.     
 48  *      echo $event->title();
 49  * }
 50  * </code>
 51  *
 52  * <code>
 53  * // Output a formatted list of all events.
 54  * $events = new Theater_Event_List;
 55  * echo $events;
 56  * </code>
 57  *
 58  * See [Theater_Event_List()](class-Theater_Event_List.html) for more examples.
 59  *
 60  * ### Event dates
 61  * <code>
 62  * // Retrieve a list of all event dates.
 63  * $dates = new Theater_Event_Date_List;
 64  * foreach ( $dates() as $date ) {
 65  *      // $date is a Theater_Event_Date object.     
 66  *      echo $date->title();
 67  * }
 68  * </code>
 69  *
 70  * <code>
 71  * // Output a formatted list of all dates.
 72  * $dates = new Theater_Event_Date_List;
 73  * echo $dates;
 74  * </code>
 75  *
 76  * See [Theater_Event_Date_List()](class-Theater_Event_Date_List.html) for more examples.
 77  *
 78  * ## Extending Theater for WordPress
 79  * You can safely add extra functionality by using the `theater/loaded` action hook:
 80  * <code>
 81  * function theater_example_loader() {
 82  *      // Add your custom code below...
 83  * }
 84  * add_action( 'theater/loaded', 'theater_example_loader' );
 85  * </code>
 86  * See this [Example Extension](https://github.com/slimndap/wp-theatre-example-extension) for a full example.
