Detailed Description

This class implements an implicit solvation force using the GB/VI model.

To use this class, create a GBVIForce object, then call addParticle() once for each particle in the System to define its parameters. The number of particles for which you define GB/VI parameters must be exactly equal to the number of particles in the System, or else an exception will be thrown when you try to create a Context. After a particle has been added, you can modify its force field parameters by calling setParticleParameters().
