Diese Klasse implementiert den Gerätemanager einer ORBIT-Anwendung.
**Parameter**
``core``
Ein Verweis auf den Anwendungskern der ORBIT-Anwendung.
Eine Instanz der Klasse :py:class:`Core`.
**Beschreibung**
Der Gerätemanager baut eine Verbindung zu einem TinkerForge-Server auf,
ermittelt die angeschlossenen Bricks und Bricklets und stellt
den Komponenten in den Jobs die jeweils geforderten Geräte zur Verfügung.
Dabei behält der Gerätemanager die Kontrolle über den Gerätezugriff.
Das bedeutet, dass der Gerätemanager die Autorität hat, einer Komponente
ein Gerät zur Verügung zu stellen, aber auch wieder zu entziehen.
Eine Komponente bekommt ein von ihm angefordertes Gerät i.d.R. dann zugewiesen,
wenn die Komponente aktiv und das Gerät verfügbar ist. Wird die Verbindung
zum TinkerForge-Server unterbrochen oder verliert der TinkerForge-Server
die Verbindung zum Master-Brick (USB-Kabel herausgezogen), entzieht
der Gerätemanager der Komponente automatisch das Gerät, so dass eine
Komponente i.d.R. keine Verbindungsprobleme behandeln muss.
Umgesetzt wird dieses Konzept mit Hilfe der Klassen :py:class:`SingleDeviceHandle`
und :py:class:`MultiDeviceHandle`.
