/**
* API: Topics & Posts
*
* IMPORTANT: This API DOESN'T check permissions, etc
* So, it's entirely possible to add replies to closed topics
* and to post new topics where the user doesn't normally have
* permission.
* EXAMPLE USAGE
* <code>
* $api = new api_topics_and_posts();
* $api->ipsclass =& $this->ipsclass;
* // ADD POST REPLY
* $api->set_author_by_name('matt');
* $api->set_post_content("<b>Hello World!</b> :D");
* $api->set_topic_id( 100 );
* # Default for show_signature is 1, added here for completeness
* $api->post_settings['show_signature'] = 1;
* # Optionally turn off rebuild to not rebuild topic, forum and stats
* # $api->delay_rebuild = 1;
* $api->create_new_reply();
* // ADD NEW TOPIC
* $api->set_author_by_name('matt');
* $api->set_post_content("<b>Hello World!</b> :D");
* $api->set_forum_id( 10 );
* $api->set_topic_title('Hello World');
* $api->set_topic_description('I am the description');
* $api->set_topic_state('open');
* $api->create_new_topic();
* </code>
