 * ParticleBalancer - functions for performing load balancing for
 *    particles using a particle density field.
 *
 * Load balancing for particles is performed by constructing a BareField
 * object over the domain occupied by the particles, and filling this field
 * with the density of the particles.  The Field is then repartitioned by
 * using one of the Field repartitioning algorithms, and the resulting
 * Field layout is given to the Particle object, which then redistributes
 * the particles.
