[CIG-SHORT] cells connected to a fault vertex

[Birendra jha]

Hi

How can I get cells connected to a given fault vertex, both positive and negative side cells? I used sieve's orientedStar with v_positive and v_negative but this gives all faces at the vertex plus the vertex number of that vertex. Do I need to use sieve's support on individual faces, as the second step, to get the cells on both sides of each face? This will give duplicate cell numbers. 

Thanks
