NAME

       Bio::Phenotype::MeSH::Term - A MeSH term

SYNOPSIS

         use Bio::Phenotype::MeSH::Term;

         # create a term object
         my $term = Bio::Phenotype::MeSH::Term->new
             (-id => 'D000001',
              -name => 'Dietary Fats',
              -description => 'dietary fats are...'
             );

         # get a Bio::Phenotype::MeSH::Twig somehow...
         $term->add_twig($twig1);

DESCRIPTION

       This class keeps information about MeSH terms. MeSH stands for Medical Subject Headings
       and is one of the ways for annotaing biomedical literature.  The terminology is maintained
       by National Library of Medicine of USA . See http://www.nlm.nih.gov/mesh/meshhome.html.

       In addition to id, name and description a term can know about its surrounding terms
       (Bio::Phenotype::MeSH::Twig) in the term hierarchy.

       This class is mainly used from Bio::DB::MeSH which retrieves terms over the Web.

        Function: Set/get for the id.
        Returns : A id [scalar].
        Args    : A id [scalar] (optional).

   name
        Title   : name

   Twig management
       Each MeSH term belongs to a complex tree like hierarchy of terms where each term can
       appear multiple times. The immediately surrounding nodes of the tree are modelled in
       twigs.
