PullToRefreshView

It is:
 - a pull-to-refresh implementation
 - very easy to implement
 - doesn't suck

To implement it:
 - add the three files (PullToRefreshView.{h,m} and arrow.png) to your project
 - #import "PullToRefreshView.h"
 - add an ivar: PullToRefreshView *pull; // or whatever you want to name it
 - in loadView or viewDidLoad, add this (and be sure to release in dealloc/viewDidUnload, etc):
    pull = [[PullToRefreshView alloc] initWithScrollView:<your scroll view here>];
    [pull setDelegate:self];
    [<your scroll view here> addSubview:pull];
 - implement two delegate methods:
    // called when the user pulls-to-refresh
    - (void)pullToRefreshViewShouldRefresh:(PullToRefreshView *)view;
    // called when the date shown needs to be updated, optional
    - (NSDate *)pullToRefreshViewLastUpdated:(PullToRefreshView *)view;
 - call -finishedLoading on the PullToRefreshView when you finished loading (or got an error, etc)
 - that's it! no need to forward on UIScrollView delegate methods or anything silly like that.
