A Delaunay complex for a set of d-dimensional points is a tesselation of the points such that no point is inside
the circumscribing hypersphere of the d-simplices (for the 3D case: Tetrahedra).

Returns true if this point dominates point q (i=0,1,2 is the most important coordinate,
j=0,1,2 is the second most important coordinate and k=0,1,2 is the least important coordinate).
