rtdCubeDisplay displays FITS cube images for the real-time display. By specifying a FITS cube file
(option -f) and a camera name (option -c) the images are extracted from the file and an image event is
sent to the rtdServer. In order to display the image a rtd widget application e.g. 'rtd' must register to
the same camera name as specified above. For the 'rtd' application this is done by setting the
RTD_CAMERA environment.

FITS cube images
-c<cameraname>

-l Loop indefinetly
-tmsec
