A "OneAxisScan" that will rotate around the omega angle.
an OmegaScan has the advantage that the omega axis is always
perpendicular to the beam and parallel to the detector. Hence
omega scans are the safest bet to collect data in an efficient
way. The problem is that omega scans can in general not be very
long, especially at low values of dx and at high absolute
values of kappa.
See the description of the superclass OneAxisScan.

)
Return an Impact() object corresponding to the scan.
parameters:
- dataset
the Dataset() that should be simulated.
optional parameters:
- durationmax
maximal acceptable reflection duration factor. If not
specified, the duration limit for this scan is used.
- detectorsizemargin
the outside margin of the detector
(in mm) that should not be used for
predictions.
