/*!
 A Parse Framework Installation Object that is a local representation of an
 installation persisted to the Parse cloud. This class is a subclass of a
 <PFObject>, and retains the same functionality of a PFObject, but also extends
 it with installation-specific fields and related immutability and validity
 checks.

 A valid `PFInstallation` can only be instantiated via
 <[PFInstallation currentInstallation]> because the required identifier fields
 are readonly. The <timeZone> and <badge> fields are also readonly properties which
 are automatically updated to match the device's time zone and application badge
 when the `PFInstallation` is saved, thus these fields might not reflect the
 latest device state if the installation has not recently been saved.

 `PFInstallation` objects which have a valid <deviceToken> and are saved to
 the Parse cloud can be used to target push notifications.
