/*
The superfluid module handles all logic in relation to
the superfluid staking feature on Osmosis. Namely:
- Methods to lock funds and mint synthetic osmo for staking
- Daily minting and burning of the purpose of adjusting synthetic osmo lockups.
- Staking reward distribution via the intermediary account.
