 I've committed a GeometryNoder class with r3593 with which doing some
 noding tests. If I try to use SimpleSnapRounder noder rather than the
 IteratedNoder (or SimpleNoder) I get a completely wrong answer on the
 simpest case:

 LINESTRING(0 0, 10 10, 10 0, 0 10)

 There's something deeply wrong in the code and the whole Noding interface
 is overly confusing (probably due to memory management not correctly
