generateBoundaryLayer[{{hx1,hy1},{hx2,hy2},...},options] returns an artificial layer of cells surrounding a convex hull.

The input to generateBoundaryLayer must be a list of two-dimensional coordinates {{x_h1,y_h1},{x_h2,y_h2},...} specifying the convex hull of the desired set of points.The points do not have to be sorted.

For three-dimensional data, use generateBoundaryLayer3D.

If the convex hull is not known it can be calculated from the actual points {{x₁,y₁},{x₂,y₂},...} as follows:

	points={{x1,y1},{x2,y2},...};
	v=vertexCoordinates/.convexHull[points];

and then the boundary layer can be calculated as:

	generateBoundaryLayer[v,options];

Options:

traceqhull→False
boundaryCellDiameter→diameter of artificial cell (required option)
