9.2: Using CLTV in Scripts

NOTE: This is a draft in progress, so that I can get some feedback from early reviewers. It is not yet ready for learning.

OP_CHECKLOCKTIMEVERIFY (or CLTV) is the natural complement to nLockTime. It moves the idea of locking transactions by an absolute time or blockheight into the realm of opcodes, allowing for the locking of individual UTXOs.
