/*!
A mutator applies mutations (random, usually small changes) to a
set of organisms. Mutation is highly dependent on the type of
organism. In traditional genetic algorithms, a mutation flips one
or more bits in an integer (i.e., chromosome). Evolving a path for
the Traveling Salesman Problem involves complex mutations that
maintain valid permutations of destination points.

A virtual destructor. By default, it does nothing; this is
a placeholder that identifies this class as a potential base,
ensuring that objects of a derived class will have their
destructors called if they are destroyed through a base-class
pointer.
