* Maintenance of web-sites can often cause unexpected headaches, particularly

* needs to change due to an added or removed column. This plug-in function
* will match a given string to the title of a column in the table and return
* the column index, helping to overcome this problem.

* @param {string} sCol Column title to search for
* @returns {integer} Column index, or -1 if not found

* table.fnGetColumnIndex( 'Browser' );
