* - made Code/GraphMol/DistGeomHelpers/testDgeomHelpers.cpp and Code/GraphMol/DistGeomHelpers/Wrap/testDistGeom.py
more robust against very small coordinate variations which may induce UFF energy variations in the 1-kcal/mol range.
This was observed in a single case using the MinGW 32-bit g++ compiler. The check for identity of conformations
between single- and multi-threaded runs is now complemented by a 3D coordinate MSD check
* - lowered the energy tolerance to 1.0 kcal/mol
* - added rdkitBuild string with compile-time information
- added runtime check in Code/GraphMol/DistGeomHelpers/testDgeomHelpers.cpp
and Code/GraphMol/DistGeomHelpers/Wrap/testDistGeom.py
to use more lenient tolerances with MinGW compilers
