The class LampWheel class simulates the behavior of a very simple lamp wheel using an asynchronous method to rotate it.

The component reads the wheel data from the CDB. The lamp wheel is caracterized by a description, a number of available slots and a description of the used slots. All these data reside on the CDB. In particular, the number of defined slots is not defined a priori but is retrieved by parsing the CDB record for the component.

At startup, the component read the description of the wheel from the CDB and stores the configuration into a list. The move method moves the wheel to the position defined for the passed slot number. The position is read from the list (i.e. from the CDB). A log message inform the user about the selected lamp.
