Synopsis

The HTML Formatter returns data formatted into a HTML table
for a BioMart query's ResultTable

Description

When given a BioMart::ResultTable containing the results of
a BioMart::Query the HTML Formatter will return HTML 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
