NAME

       Bio::Tree::AlleleNode - A Node with Alleles attached

SYNOPSIS

         use Bio::Tree::AlleleNode;

DESCRIPTION

       AlleleNodes are basic Bio::Tree::Nodes with the added ability to add Genotypes alleles as
       defined by the Bio::PopGen::IndividualI interface.  Genotypes are defined by the
       Bio::PopGen::GenotypeI interface, you will probably want to use the Bio::PopGen::Genotype
       implementation.

       This is implemented via containment to avoid multiple inheritance problems.  Their is a
       Bio::PopGen::Individual object which handles the Bio::PopGen::IndividualI interface, and
       is accessible via the Bio::Tree::AlleleNode::individual method.
