GRIDCHECK Check grid for errors.

[ N_ERR, CIND ] = GRIDCHECK( G, ISWARN, I_CHECK ) Checks a grid G for errors. N_ERR returns the number of errors found. CIND is a cell array giving the indices to incorrectly oriented cells, collapsed cells (with zero volume/area), and non-convex cells. ISWARN is a flag to enable/disable warnings. I_CHECK is a flag to choose check/test type (1 = test Jacobian determinant (default), 2 = test if polygon points are in clockwise order, 3 = split hexahedra into six tetrahedra).
