[akloboucnik]

• [x] determine mining algorithm for blocks must be locked in ("Sliced Cosine Distance" REF: https://gist.github.com/mmpmm/32b513c91fc186bc2971d6566af34ba2)
• [ ] create versioning flag for upgrading/edits to the algorithm (Ex. Monero anti-ASIC upgrade / Ethereum Frontier -> Homestead -> Byzantium).
• [ ] determine mining algorithm for transactions must be locked in
• [ ] miner needs to query it's TX pool for the best combination of transactions that have optimum fees and distances (optionally considering it's own Emblem balance if it has one)
