=head1 NAME
BioMart::Formatter::HTML_36
=head1 SYNOPSIS
The HTML_36 Formatter returns data formatted into a HTML_36 table
for a BioMart query's ResultTable
=head1 DESCRIPTION
When given a BioMart::ResultTable containing the results of
a BioMart::Query the HTML_36 Formatter will return HTML_36 formatted tabular
output. The getDisplayNames and getFooterText can be used to return
appropiately formatted headers and footers respectively. If hyperlink
templates are defined for the attributes in the Dataset's ConfigurationTree
then appropiate hyperlinks will be calculated for each cell of the table.
Addition of any extra attributes to the Query that may be required for this
hyperlink formatting is handled in this Formatter
