[vtkusers] Marching wedge : BUG ?

[Philippe Guerville]

I used vtkCutter to cut trough an unstructured grid with a plane.
In the case of wedges, I found some mistakes in the 
triCases array (File vtkWedges.cxx).

The following edge lists are wrong : 26, 45, 47, 60, 61, 62

The correct edge lists are :
{{ 6, 0, 1, 6, 1, 5, 5, 1, 4, -1, -1, -1, -1}}, //26
{{ 0, 3, 1, 3, 4, 1, -1, -1, -1, -1, -1, -1, -1}}, //45
{{ 7, 3, 4, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1}}, //47
{{ 7, 1, 6, 6, 1, 2, -1, -1, -1, -1, -1, -1, -1}}, //60
{{ 0, 7, 1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1}}, //61
{{ 0, 6, 2, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1}}, //62
