-"""Mixin for keeping parameters persistent
-
-For hardware not keeping parameters persistent, we might want to store them in Frappy.
-
-The following example will make 'param1' and 'param2' persistent, i.e. whenever
-one of the parameters is changed, either by a change command or by access from
-an other interface to the hardware, it is saved to a file, and reloaded after
-a power down / power up cycle. In order to make this work properly, there is a
-mechanism needed to detect power down (i.e. a reading a hardware parameter
-taking a special value on power up).
-
-An additional use might be the example of a motor with cyclic reading of an
-encoder value, which looses the counts of how many turns already happened on
-power down.
-This can be solved by comparing the loaded encoder value self.encoder with a
-fresh value from the hardware and then adjusting the zero point accordingly.
-
-
-class MyClass(PersistentMixin, ...):
-    param1 = PersistentParam(...)
-    param2 = PersistentParam(...)
-    encoder = PersistentParam(...)
-
-    ...
-
-    def read_encoder(self):
-        encoder = <get encoder from hardware>
-        if <power down/power up cycle detected>:
-            self.loadParameters()
-            <fix encoder turns by comparing loaded self.encoder with encoder from hw>
-        else:
-            self.saveParameters()
