/**
* Sample plugin main class
*
* Each plugin requires a main class to interact with the StatusNet system.
*
* The main class usually extends the Plugin class that comes with StatusNet.
*
* The class has standard-named methods that will be called when certain events
* happen in the code base. These methods have names like 'onX' where X is an
* event name (see EVENTS.txt for the list of available events). Event handlers
* have pre-defined arguments, based on which event they're handling. A typical
* event handler:
*
* function onSomeEvent($paramA, &$paramB)
* {
* if ($paramA == 'jed') {
* throw new Exception(sprintf(_m("Invalid parameter %s"), $paramA));
* }
* $paramB = 'spock';
* return true;
* }
*
* Event handlers must return a boolean value. If they return false, all other
* event handlers for this event (in other plugins) will be skipped, and in some
* cases the default processing for that event would be skipped. This is great for
* replacing the default action of an event.
*
* If the handler returns true, processing of other event handlers and the default
* processing will continue. This is great for extending existing functionality.
*
* If the handler throws an exception, processing will stop, and the exception's
* error will be shown to the user.
*
* To install a plugin (like this one), site admins add the following code to
* their config.php file:
*
* addPlugin('Sample');
*
* Plugins must be installed in one of the following directories:
*
* local/plugins/{$pluginclass}.php
* local/plugins/{$name}/{$pluginclass}.php
* local/{$pluginclass}.php
* local/{$name}/{$pluginclass}.php
* plugins/{$pluginclass}.php
* plugins/{$name}/{$pluginclass}.php
*
* Here, {$name} is the name of the plugin, like 'Sample', and {$pluginclass} is
* the name of the main class, like 'SamplePlugin'. Plugins that are part of the
* main StatusNet distribution go in 'plugins' and third-party or local ones go
* in 'local'.
*
* Simple plugins can be implemented as a single module. Others are more complex
* and require additional modules; these should use their own directory, like
* 'local/plugins/{$name}/'. All files related to the plugin, including images,
* JavaScript, CSS, external libraries or PHP modules should go in the plugin
* directory.
