Profile angle calculations

[vidanovic]

Profile angle calculations should not depend on Incoming/Outgoing direction. Coordinate system is entirely changing and Theta and Phi are calculated in the same way for either Incoming or Outgoing directions.
Should be this:

Windows-CalcEngine/src/SingleLayerOptics/src/BSDFDirections.cpp

Lines 97 to 100 in 6c7f0a5

	double BSDFDirections::correctPhiForOutgoingDirection(double currentPhi)
	{
	return (currentPhi > 360) ? currentPhi - 360 : currentPhi;
	}

instead of:

Windows-CalcEngine/src/SingleLayerOptics/src/BSDFDirections.cpp

Lines 99 to 106 in e2a05f6

	double BSDFDirections::correctPhiForOutgoingDireciton(const BSDFDirection & t_Side,
	const size_t nPhis,
	double currentPhi)
	{
	double correctedPhi =
	(t_Side == BSDFDirection::Outgoing && nPhis != 1) ? currentPhi + 180 : currentPhi;
	return (correctedPhi > 360) ? correctedPhi - 360 : correctedPhi;
	}

Fixed in Version_1.0.49

This fix will be the reason why IGUs with XML layers will give small differences in optical results.
