Alternative data provision for quicker changes + animation support

[GoogleCodeExporter]

The current approach of having to implement delegate methods (via protocol or 
data source delegate) is one of the biggest restrictions in coreplot related to 
data provision. It prevents everything data-related from being quickly 
changeable (especially for animation). A better approach is using an array 
controller and KVO. The protocol driven approach only adds to the complexity as 
most of us have their data in an array or tree controller anyway.

This holds true for all data provided by said delegates (e.g. also labels, pie 
offsets etc.).

Core Plot supports bindings on Mac OS X for the plot data and has since the 
beginning. We can add bindings support for the other data elements.

The Mac version of CPTTestApp demonstrates data bindings. The other example 
apps use the datasource methods so that the code is cross platform since 
bindings are not supported on iOS.

Ah, I really missed this part. Thanks for pointing this out. In fact the 
existing binding in scatter plots is already a good start. Adding support for 
the other elements would definitely be a plus, especially when you want to 
animate them. Please don't forget the other plot types (I'm especially waiting 
for bound pie offsets, so I can animate them).
