Sanity check needed in Ng_RestrictMeshSizeBox
NETGEN is an automatic 3d tetrahedral mesh generator

In "nglib/nglib.cpp" - void Ng_RestrictMeshSizeBox (Ng_Mesh * mesh, double * pmin, double * pmax, double h)
Needs a sanity check for allowing only "h>0".
I've gotten stuck in an endless loop because h was below zero, while doing some tests with enGrid.
