Detailed Description

Holds direction in which to split cell (in fact a local coordinate axes). Information is a label and a direction.

The direction is the normal direction to cut in. The label's meaning depends on whether the info is on a cell or on a face:

in cell: edge that is being cut. (determines for hex how cut is)
in face: local face point that is being cut or -1.

(-1) : cut is tangential to plane
(>= 0): edge fp..fp+1 is cut

(has to be facepoint, not vertex since vertex not valid across processors whereas f[0] should correspond to f[0] on other side)

The rule is that if the label is set (-1 or higher) it is used (topological information only), otherwise the vector is used. This makes sure that we use topological information as much as possible and so a hex mesh is cut purely topologically. All other shapes are cut geometrically.
