//  If your TableViewCells are in Xib files and you name them in some convencion
//  described with regular expression, you can load them into a table like this:
//  In your viewDidLoad method call
//     [[VIOSXibLoader defaultLoader] loadXibsForTableView:self.tableView
//                                             withPattern:@"^MyModelClassName(\\w*)TableViewCell$"];
