This class retrieves a term from the Medical Subject Headings database
by the National Library of Medicine of \s-1USA.\s0 See
<http://www.nlm.nih.gov/mesh/meshhome.html>. It uses the latest
data available (updates happen on weekdays). If it fails, an archive
cgi scripts accessing older data from previous year is used.
.PP
This class implements Bio::SimpleAnalysisI and wraps its methods under
get_exact_term.

By default, web access uses WWW::Mechanize, but in its absence
falls back to bioperl module Bio::WebAgent which is a subclass of
LWP::UserAgent.

\&  Title   : get_exact_term
\&  Usage   : $s = $db\->get_exact_term($value);
\&  Function: Retrieve a single MeSH term using a unique ID or exact name.
\&  Example :
\&  Returns : a Bio::Phenotype::MeSH::Term object
\&  Args    : scalar, UID or name of a MeSH term
.Ve
.PP
The returned term object contains information about the immediate
vincinity of the term in the terminology hierarchy. See
Bio::Phenotype::MeSH::Twig.
