/*!
This consists of setting 1-2, 1-3 and 1-4 distance based on bond lengths,
bond angles and torsion angle ranges. Optionally 1-5 bounds can also be set,
in particular, for path that contain rigid 1-4 paths.
The final step involves setting lower bound to the sum of the vdW radii for
the remaining atom pairs.
\param mol The molecule of interest
\param mmat Bounds matrix to the bounds are written
\param set15bounds If true try to set 1-5 bounds also based on topology
\param scaleVDW If true scale the sum of the vdW radii while setting lower
bounds
so that a smaller value (0.7*(vdw1 + vdw2) ) is used for
paths
that are less five bonds apart.
<b>Note</b>
For some strained systems the bounds matrix resulting from setting 1-5 bounds
may
fail triangle smoothing. In these cases it is recommended to back out and
recompute the bounds matrix with no 1-5 bounds and with vdW scaling.
