Centroid computes the centroid of a two-dimensional sets of intensity measurements. It takes a single input, a Grid< float >, which contains both the intensity measurements and the pixel geometry. It has three outputs: the x and y centroids as separate scalars, and the two together, in a Vector< float >.

Parameters
None
Inputs
grid	Grid<float>	Input grid (usually output from a focal plane camera).
Outputs
x	float	X-coordinate of centroid (same units as grid spacing).
y	float	Y-coordinate of centroid (same units as grid spacing).
v	Vector<float>	X and Y coordinates of centroid (same units as grid spacing)
