noexcept

Compute the next required proof of work using an absolutely scheduled exponentially weighted target (ASERT).

With ASERT, we define an ideal schedule for block issuance (e.g. 1 block every 600 seconds), and we calculate the difficulty based on how far the most recent block's timestamp is ahead of or behind that schedule. We set our targets (difficulty) exponentially. For every [nHalfLife] seconds ahead of or behind schedule we get, we double or halve the difficulty.
