0023746: IGES wheel model fails to load when OCCT unit is meters

Browse Source 
Add check for too small distances during edges reordering
Fix writing TrimmedSurface (Type 144).
Fix checking for too small distances between loops of edges during edge's reordering.
Add checking for too small BSpline segments during reading and writing IGES.
Fix wire splitting by adding checking that vertexes same not only in 3d, but in 2d too.
use tolerance of vertexes recomputed through resolution surface, not 2d curves.
Adding test case for this fix
Modified test case bugs iges bug23746 and cases in group de according to new reference data
