18 * Groups are used for populations and subpopulations.  They are slightly
19 * different from Prototypes in a few important ways.
20 *
21 * A Group instance typically is set up with setup(...) and then <i>used</i>
22 * (unlike in a Prototype, where the prototype instance is never used,
23 * but only makes clones
24 * which are used).  When a new Group instance is needed, it is created by
25 * calling emptyClone() on a previous Group instance, which returns a
26 * new instance set up exactly like the first Group instance had been set up
27 * when setup(...) was called on it.
28 *
29 * Groups are Serializable and Cloneable, but you should not clone
30 * them -- use emptyClone instead.
