2Scales mutation across range of parameter
3Description::
4The mutation_scale is a fraction in the range [0, 1] and is meant to help
5control the amount of variation that takes place when a variable is mutated.
6Its behavior depends on the selected \c mutation_type. For \c offset_normal
7and \c offset_cauchy, \c mutation_scale is multipled by the range of the
8variable being mutated to obtain the standard deviation of the offset. For
9\c offset_uniform, the range of possible deviation amounts is +/- 1/2 *
10(mutation_scale * variable range).
