Mesh: QuadTree: Creation
========================
You can give the refine method a function, which is evaluated on every cell
of the TreeMesh.
Occasionally it is useful to initially refine to a constant level
(e.g. 3 in this 32x32 mesh). This means the function is first evaluated
on an 8x8 mesh (2^3).
