performSelector reimplementation with variable number of params/types and return type.
/*
You can use this to call deprecated methods without warnings (supporting old sdk's for example)
or, you can use it in place of performSelector: where you need non-object params, or multiple
params.
ie: ...
int result = 0;
int index = 12;
NSArray *array = myArray;

Paul Heckel's Diff Algorithm

[Isolating Differences Between Files][paper]

Advantage over Other Algorithms

The diff output is more specific:

[I]f a whole block of text is moved, then all of it, rather than just the beginning and end, is detected as changed.

>The algorithm described here avoids these difficulties. It detects differences that correspond very closely to our intuitive notion of difference.

Works because a lot of calls internally call setNeedsDisplay or setNeedsLayout. Won't catch everything, but it's very lightweight and usually does the job.You might n…
