g = Grid(0*ss+xmin,0*ss+ymin, 4*ss+xmin,4*ss+ymin, ss,gridType='distance')
line = ( (0,1.5),(1,1.5))
# Single cell - vert
r = g.getLineCellsWithCrossings(.25,0, .75,0.,verbose=True)
#print 'r',r
cell,frac1,frac2,dist = r[0]
self.failUnlessEqual((0,0),cell)
self.failUnlessAlmostEqual(0.,frac1)
self.failUnlessAlmostEqual(1.,frac2)
self.failUnlessAlmostEqual(0.5,dist)
# Single cell - horz
