> Define print format macros for NSInteger & NSUInteger
> 
> The size of NSInteger and NSUInteger varies between 32-bit and 64-bit
> architectures, however does not provides macro to safely format them
> and instead recommend casting the value to the larger version that is
> used on 64-bit architecture.
> 
> Using a cast could cause some formatting to be missed (if the type of
> a variable changes), so instead we define our own macros to format those
> types safely.
