"""A template method class that can register itself with a `Registry.
This class should be subclassed by various implementations. Subclasses should provide all relevant attributes, as documented below.
Attributes ---------- camera : `str` Name of the camera. Must be provided by subclass. physicalFilters : `list` List of PhysicalFilter entries (each entry being a dict). sensors : `list` List of Sensor entries (each entry being a dict). """
