based on Chipmunk cpArray.
ccArray is a faster alternative to NSMutableArray, it does pretty much the same thing (stores NSObjects and retains/releases them appropriately). It's faster because:
- it uses a plain C interface so it doesn't incur Objective-c messaging overhead
- it assumes you know what you're doing, so it doesn't spend time on safety checks (index out of bounds, required capacity etc.)
- comparisons are done using pointer equality instead of isEqual
There are 2 kind of functions:
- ccArray functions that manipulates objective-c objects (retain and release are performed)
- ccCArray functions that manipulates values like if they were standard C structures (no retain/release is performed)
