Discussion of [UITableView tableView heightForHeaderInSection]
This method allows the delegate to specify section headers with varying heights.

Special Considerations
Prior to iOS 5.0, table views would automatically resize the heights of headers to 0 for sections where tableView:viewForHeaderInSection: returned a nil view. In iOS 5.0 and later, you must return the actual height for each section header in this method.
