* %D
* Instrument to get basic test output from random number generator.
*
* The instrument generates 2 randon numbers pr. particle using randpm1(),
* encoded into the particle x and y coordinates.
*
* For a low statistics, one may e.g. check that setting the seed gives
* varied output or fixing the seed gives fixed output·
*
* %Example: Ncount=1000000 Detector: PSD_I=1.0
*
* %P
* Ncount: [1] Specify statistics
* seed: [1] Specify RNG seed
