/** A view controller giving the user information about how to use the sensor. 
  * It also contains a part where the user can try to swiep his/her finger. 
  * 
  * The practice controller can be placed in a UINavigationController. It will 
  * set a default title that will be shown on the navigation bar.
  *
  * Example:
  * 
  *  PBPracticeController* practiceController = [[PBPracticeController alloc] init];
  *  UINavigationController* navController = [[UINavigationController alloc] init];
  *  
  *  [navController pushViewController:practiceController animated:NO];
  *  
  * The practice controller can also be placed in a tab bar controller. It will 
  * create a default tab bar item that will be shown on the tab bar. It is 
  * recommended to place the practice controller in a navigation controller and 
  * then place the navigation controller in the tab bar controller to also get 
  * the correct navigation bar for the practice controller.
  *
  * Example:
  * 
  *  PBPracticeController* practiceController = [[PBPracticeController alloc] init];
  *  UINavigationController* navController = [[UINavigationController alloc] init];
  *  UITabBarController* tabBarController = [[UITabBarController alloc] init];
  *  
  *  [navController pushViewController:practiceController animated:NO];
  *  [tabBarController setViewControllers:[NSArray arrayWithObjects:navController, nil]];
