These methods all expect to be passed positive integers, undef or zero,
other values could (and likely will) do something unpredictable.

=over 4

=item C<mutate([num, ref to hash of probs & methods])>

This will call at random one of the other mutation methods.
It will repeat itself I<num> times.  If passed a reference
to a hash as its second argument, it will use that to
decide which mutation to attempt.

This hash should contain keys which fit $1 in C<mutate_(.*)>
and values indicating the weight to be given to that method.
The module will normalise this nicely, so you do not have to.
This lets you define your own mutation methods in addition to
overriding any you do not like in the module.

=item C<mutate_insert([num, pos])>

Inserts a single token into the string at position I<pos>.

I<length> and then splices it into the gene before I<pos2>.

=item C<mutate_remove([num, pos, length]))>

Deletes I<length> tokens from the gene, starting at I<pos>. Repeats
I<num> times.

=item C<mutate_minor([num, pos])>

This will mutate a single token at position I<pos> in the gene 
into one of the same type (as decided by the object's C<generate_token>
method).

=item C<mutate_major([num, pos])>

This changes a single token into a token of any token type.
Token at postition I<pos>.  The token is produced by the object's
C<generate_token> method.

=item C<mutate_switch([num, pos1, pos2, len1, len2])>

of mutations carried out (not the number of tokens affected).
