DCT-II implementation using the vDSP on the iOS (and also OSX?)

	/* This implementation does DCT-II on iOS, using the iOS vDSP FFT methods. Supposedly this is faster than in plain C (i.e. FFTW), but I didn't do any tests to support this claim. For one thing, as far as I understand it, doing DCT takes less clock cycles than FFT, and using this code we do an FFT of size 2N for a DCT of size N (and then some post processing. Anyone is welcome to comment :)

	This code was developed using the following 2 sources, and I owe great gratitude to their authors: http://developer.apple.com/library/ios/#documentation/Performance/Conceptual/vDSP_Programming_Guide/UsingFourierTransforms/UsingFourierTransforms.html and http://www.hydrogenaudio.org/forums//lofiversion/index.php/t39574.html

	I don't claim I understand everything I do, but the thing is, it works -- as in, it gives me the same result as jtransform with scaling on :) And it's fast enough for my use: on the iPhone 4S I can get 320 DCTs of length 2048 per second. Perhaps I can improve this with some further tweaking (although I'
