std::pair<int, int64_t> CalculateSequenceLocks	(	const CTransaction &	tx,
		int	flags,
		std::vector< int > *	prevHeights,
		const CBlockIndex &	block
	)

Calculates the block height and previous block's median time past at which the transaction will be considered final in the context of BIP 68.

Also removes from the vector of input heights any entries which did not correspond to sequence locked inputs as they do not affect the calculation.
