Description
Internal use.
This method is called by the Series to create an internal grid template upon which to base the Surface or Contour plots.

If you pass exact grid X and Z values to the Series (ie, correlative integer numbers starting from zero), the FillGridIndex method will do nothing.

If the X and Z values are floating point, or they aren't ordered, the FillGridIndex method will construct a grid and sort the X and Z coordinates.

The resulting grid will be then used as an index for every point to display.

If you have XYZ values that cannot be fitted on a square grid, you can use the TriSurface Series.
