Public: Initialize a new HTMLTable with the specified table-data as parse
         by machinist (or Nokogiri).

 parsed_table - A Nokogiri::HTML::Document or Nokogiri::XML::Element scoped
                to only the HTML table you are interested in.  Technically
                speaking, you could pass in more content than just the
                <table> element and it would likely work fine, but that is
                the anticipated content structure.

 Returns an instance of HTMLTable
 Public: Retrieve the content of all the <td> elements from the table,
         except for the first row.

 Returns an Array of Array elements, each one being the content from one
   row of the table.  The returned content does NOT include the first row,
   as it is assumed to be the heading of the table.
