	The direction orthogonal to the shift direction.
double	layerLow {0.}
	The lowest bin edge in the grid along the direction opposite to the shift direction, it is needed to extract the correct index of the shifts vector.
double	layerPitch {0.}
	The layer pitch it is needed to extract the correct index of the shifts vector.
AxisDirection	shiftDir {AxisDirection::AxisX}
	The direction along the shift direction.
std::vector< double >	shifts
	The vector with the shifts per layer if empty, exception is thrown.

Detailed Description

A struct to access the shifted center of surface applying a shift on the corresponding coordinate.

This generator will provide only one filling point and hence only a single bin in the indexed grid.
