/**
* Resets the registry.
*
* The criteria for what gets reset is based on what can be shared between sites on the same request when switch_to_blog
* is used in a multisite install. Here is a list of things that are NOT reset.
*
* - $_dependency_map
* - $_class_abbreviations
* - $NET_CFG (EE_Network_Config): The config is shared network wide so no need to reset.
* - $REQ: Still on the same request so no need to change.
* - $CAP: There is no site specific state in the EE_Capability class.
* - $SSN: Although ideally, the session should not be shared between site switches, we can't reset it because only one Session
* can be active in a single request. Resetting could resolve in "headers already sent" errors.
* - $addons: In multisite, the state of the addons is something controlled via hooks etc in a normal request. So
* for now, we won't reset the addons because it could break calls to an add-ons class/methods in the
* switch or on the restore.
* - $modules
* - $shortcodes
* - $widgets
*
* @param boolean $hard whether to reset data in the database too, or just refresh
* the Registry to its state at the beginning of the request
* @param boolean $reinstantiate whether to create new instances of EE_Registry's singletons too,
* or just reset without re-instantiating (handy to set to FALSE if you're not sure if you CAN
* currently reinstantiate the singletons at the moment)
* @param bool $reset_models Defaults to true. When false, then the models are not reset. This is so client
* code instead can just change the model context to a different blog id if necessary
*
* @return EE_Registry
