00027 
00028 Description
00029     Select cells based on cell centres inside rotatex/skewed box
00030     (parallelopiped?). Box defined as origin and i,j,k vectors.
00031     E.g. box rotated 45 degrees around z-axis with sizes sqrt(0.2^2+0.2^2)
00032     (and extra large, 200 in z direction):
00033 
00034        origin   ( 0.4 0.4 -100);
00035        i        ( 0.2 0.2    0);
00036        j        (-0.2 0.2    0);
00037        k        ( 0.0 0.0  100);
