MBSpacialViewController lets you create an arbitrarily complex map of view controllers in 2D space. Using gestures, you can navigate up, down, left, and right from any view controller. A map is automatically generated and displayed in the bottom left corner.

##Usage Usage is best explained by checking out the easy to follow sample code. Basically:

1. Create a master view controller which inherits from MBSpacialMasterViewController.
   
2. Set the master's root property to any view controller (must inherit from MBSpacialChildViewController).
   
3. Set the root's left/right/upper/lower viewController property. You can do this recursively to create a complex map of view controllers in 2D space: For example:

self.leftViewController = [some subclass of MBSpacialChildViewController];
self.upperViewController = […];
self.upperViewController.leftViewController.lowerViewController = […];

###Navigation Navigating through view controllers is done via gestures, but can also be done programatically: [self moveInDirection:MBDirectionLeft animated:YES]; where self is a subclass of MBSpacialChildViewController

###Modals If you want a view controller to be deallocated and removed from the heirarchy after it disappears, you can make it a modal:

MBSpacialChildViewController *controller = […]
controller.isModal = YES;
controller.modalPresentingViewController = self;
self.rightViewController = controller;
[self moveInDirection:MBDirectionRight animated:YES];

###Gestures By default, navigation is done via 1 finger pan. If you'd like to require 2 fingers (to avoid clash with scroll views and table views), you can do: self.panGesture.minNumberTouchesLeft = 2; This will also update the map to display 2 lines instead of 1 to indicate a two-finger swipe requirement. (Note: Minimal testing was done on this feature)

###View callbacks MBSpacialViewController doesn't use UIKit view callbacks such as viewDidAppear or viewWillAppear. Instead, we use:

-(void)spacialViewDidLoad;
-(void)spacialViewWillAppear;
-(void)spacialViewDidAppear;
-(void)spacialViewWillDisappear;
-(void)spacialViewDidDisappear;

Any view controller that is part of the view heirarchy must inherit from MBSpacialChildViewController.
