20 * IntegerVectorSpecies is a subclass of VectorSpecies with special constraints
21 * for integral vectors, namely ByteVectorIndividual, ShortVectorIndividual,
22 * IntegerVectorIndividual, and LongVectorIndividual.
23 
24 * <p>IntegerVectorSpecies can specify min/max numeric constraints on gene values
25 * in three different ways.
26 *
27 * <ol>
28 * <li> You may provide a default min and max value.
29 *      This is done by specifying:
30 *      <p><i>base</i>.<tt>min-gene</tt>
31 *      <br><i>base</i>.<tt>max-gene</tt>
32 *      <p><i>Note:</i> you <b>must</b> provide these values even if you don't use them,
33 *      as they're used as defaults by #2 and #3 below.
34 *<p>
35 * <li> You may provide min and max values for genes in segments (regions) along
36 *      the genome.  This is done by specifying:
37 *      <p><i>base</i>.<tt>num-segments</tt>
38 *      The segments may be defined by either start or end indices of genes.
39 *      This is controlled by specifying the value of:
40 *      <p><i>base</i>.<tt>segment-type</tt>
41 *      which can assume the value of start or end, with start being the default.
42 *      The indices are defined using Java array style, i.e. the first gene has the index of 0,
43 *      and the last gene has the index of genome-size - 1.
44 *      <p>Using this method, each segment is specified by<i>j</i>...
45 *      <p><i>base</i>.<tt>segment.</tt><i>j</i><tt>.start</tt>
46 *      <br><i>base</i>.<tt>segment.</tt><i>j</i><tt>.min-gene</tt>
47 *      <br><i>base</i>.<tt>segment.</tt><i>j</i><tt>.max-gene</tt>
48 *      if segment-type value was chosen as start or by:
49 *      <p><i>base</i>.<tt>segment.</tt><i>j</i><tt>.end</tt>
50 *      <br><i>base</i>.<tt>segment.</tt><i>j</i><tt>.min-gene</tt>
51 *      <br><i>base</i>.<tt>segment.</tt><i>j</i><tt>.max-gene</tt>
52 *      if segment-type value is equal to end.
53 *<p>
54 * <li> You may provide min and max values for each separate gene.
55 *      This is done by specifying (for each gene location <i>i</i> you wish to specify). 
56 *      <p><i>base</i>.<tt>min-gene</tt>.<i>i</i>
57 *      <br><i>base</i>.<tt>max-gene</tt>.<i>i</i>
58 * </ol>
59 *
60 * <p>Any settings for #3 override #2, and both override #1.
