SYNOPSIS

DESCRIPTION

 end method for phiw_wvimg object
 The indexing for the wvimg object works thus:
 For one index (eg wvimg(2)) the whole level is returned (as a vector)
 For two (eg wvimg(2,4) the quadrant from the level is returned (as a
 vector)
 For three, (wvimg(2, 5, 10)) the voxel value is returned for the
 contained object.
