+%Docstring
+ A field formatter helps to handle and display values for a field.
+
+ It allows for using a shared configuration with the editor widgets
+ for representation of attribute values.
+ Field kits normally have one single instance which is managed by the
+ QgsFieldFormatterRegistry. Custom field formatters should be registered there and
+ field formatters for use within code should normally be obtained from there.
+
+ This is an abstract base class and will always need to be subclassed.
