Detailed Description

This class implements an interaction between pairs of particles that varies harmonically with the distance between them.

To use it, create a AmoebaHarmonicBondForce object then call addBond() once for each bond. After a bond has been added, you can modify its force field parameters by calling setBondParameters().
