Compound Integrator
-------------------
The :class:`CompoundIntegrator` class is useful for cases where you want to use
multiple integration algorithms within a single simulation. It allows you to
create multiple integrators, then switch back and forth between them. For
details on how to use it, consult the API documentation.

* This class allows you to use multiple integration algorithms within a single simulation,
* switching back and forth between them. To use it, create whatever other Integrators
* you need, then add all of them to a CustomIntegrator:
*
* <tt><pre>
* CompoundIntegrator compoundIntegrator;
* compoundIntegrator.addIntegrator(new VerletIntegrator(0.001));
* compoundIntegrator.addIntegrator(new LangevinIntegrator(300.0, 1.0, 0.001));
* </pre></tt>
*
* Next create a Context, specifying the CompoundIntegrator as the Integrator to use for
* the Context:
*
* <tt><pre>
* Context context(system, compoundIntegrator);
* </pre></tt>
*
* Finally, call setCurrentIntegrator() to set which Integrator is active. That one will
* be used for all calls to step() until the next time you change it.
*
* <tt><pre>
* compoundIntegrator.setCurrentIntegrator(0);
* compoundIntegrator.step(1000); // Take 1000 steps of Verlet dynamics
* compoundIntegrator.setCurrentIntegrator(1);
* compoundIntegrator.step(1000); // Take 1000 steps of Langevin dynamics
* </pre></tt>
*
* When switching between integrators, it is important to make sure they are compatible with
* each other, and that they will interpret the positions and velocities in the same way.
* Remember that leapfrog style integrators assume the positions and velocities are offset
* from each other by half a time step. When switching between a leapfrog and non-leapfrog
* integrator, you must first adjust the velocities to avoid introducing error. This is also
* true when switching between two leapfrog integrators that use different step sizes,
* since they will interpret the velocities as corresponding to different times.

* distance of the central particle, but not necessarily of all the other particles. The cutoff may therefore exclude a subset
* of the permutations of a set of particles.
*
*
* Another common situation is that some particles are fundamentally different from others, causing the expression to be

* each other. Every particle in the first set interacts with every particle in the second set. For example, you might use
* this feature to compute a solute-solvent interaction energy, while omitting all interactions between two solute atoms
* or two solvent atoms.
