this function assigns alternating row colors to table with id=tableId

1. include this *.js file in the report page.
2. If dojo is used on the report page, make a call to paintRows() after </table>. E.g.:

3. If dojo is not used, window.onload call to paintRows() can be used. E.g.:

4. Default class names are 'even' and 'odd'.
