metRidTyp	Type of storage of ridges metrics: 0 for classic storage, 1 for special storage.
chkRidTet	if 1, avoid the creation of a tet with 4 ridge vertices

Returns: -1 if we fail, 0 if we don't split the edge, 1 if success.

Split edge \(list[0]\%6\), whose shell list is passed, introducing point ip Beware : shell has to be enumerated in ONLY ONE TRAVEL (always same sense).

2 different checks : 1) are we creating a too small edge (BUG_Split1b_SpereIso_0.125h_met) 2) in aniso and from the last wave of anatet(typchk=1): avoid the creation of a tetra with 4 ridge vertices.
