示例1: addPlugin
/**
* @brief Add a plugin.
*
* @pre Needs to be a unique new name (use refname if you want to add the same module multiple times)
*
* Will automatically resolve virtual plugins to actual plugins.
*
* Also calls the checkconf function if provided by the plugin. The checkconf function has the
* following signature: int checkconf (Key * errorKey, KeySet * config) and allows a plugin to
* verify its configuration at mount time.
*
* @see resolveNeeds()
* @param plugin
