       things we care about here: coordinates of the dofs and
       element-dof lists.
 
       We will assume only that the elements are numbered
       lexicographically, left-to-right, bottom-to-top. The order of
       the degrees of freedom will only be assumed on coarse grids. It
       can be anything on the finest grid (fineLevel.GetLevelID()==1).
 
       We further assume that the x- and y-components of velocity are
       zippered together: UX1 UY1 UX2 UY2 ETC...
