RotateSlopes reclacululates WFS slopes as if they had been measured with the subaperture locations rotated. This is useful if it is known that there is a rotation in the optical system between the DM and WFS. The rotation angle is defined as the orientation of the WFS X-Y axes relative to the orientation of the DM X-Y axes. Positive angles correspond to a counter-clockwise rotation of the WFS relative to the DM, so the slopes will appear to rotate anti-clockwise relative to the X-Y axes.

Parameters
xSubap	Vector<float>	X locations of subaperture centers in pupil plane (m)	dmModel.xMeasurementLocations()
ySubap	Vector<float>	Y locations of subaperture centers in pupil plane (m)	dmModel.yMeasurementLocations()
Inputs
rotationAngle	Recallable<float>	Rotation angle (rad); must be a "Recallable", which supports looking back in time	recallableFloat(0.0)
inSlopes	Vector<float>	Slopes from a wavefront sensor	ZeroVecF(2)
Outputs
rotSlopes	Vector<float>	Slopes rotated to new orientation.
