Create a rectilinear array of data points (Subscript[p, ij]), read off from a part of a sphere.

Recall a point (Subscript[p, ij]) on a sphere is given by

	(({{cos (Subscript[s , i])sin (Subscript[t, j])}, {sin (Subscript[s, i]) sin (Subscript[t, j])}, {cos (Subscript[t, j])}}))
	
for parameter value ((Subscript[s , i]), (Subscript[t, j])). Let  0  ⩽  (Subscript[s , i]), (Subscript[t, j])  ≤ ℼ/8. Build a 4x4 “rectangular” array of points 
on the sphere and compute the bicubc Bezier surface defined by that control mesh.

For extra credit: modify the given control mesh to somethin else interesting.
