OESymmetryFractionalToCartesian
bool OESymmetryFractionalToCartesian(OEChem::OEMolBase& mol)
Converts the unit cell fractional coordinates of the molecule to
Cartesian coordinates. Returns false if the molecule does not
have crystal symmetry.
mol must have 3D fractional coordinates assigned and crystal symmetry
set (see OESetCrystalSymmetry).
