/**
 * This is a helper class to help you work with the {@link TaskInfoQuery}, without having to care about the awful generics.
 * 
 * Example usage:
 * 
 * 	TaskInfoQueryWrapper taskInfoQueryWrapper = new TaskInfoQueryWrapper(taskService.createTaskQuery());
 *  List<? extends TaskInfo> taskInfos = taskInfoQueryWrapper.getTaskInfoQuery().or()
 * 		.taskNameLike("%task%")
 * 		.taskDescriptionLike("%blah%");
 * 	.endOr()
 * 	.list();
 * 
 * First line can be switched to TaskInfoQueryWrapper taskInfoQueryWrapper = new TaskInfoQueryWrapper(historyService.createTaskQuery());
 * and the same methods can be used on the result.
