/**

• @title Passive Strategy
• @notice Rebalancing strategy for Alpha Vault that maintains the two
• following range orders:
• 1. Base order is placed between X - B and X + B + TS.
• 2. Limit order is placed between X - L and X, or between X + TS
• and X + L + TS, depending on which token it holds more of.
• where:
• X = current tick rounded down to multiple of tick spacing
• TS = tick spacing
• B = base threshold
• L = limit threshold
• Note that after these two orders, the vault should have deposited
• all its tokens and should only have a few wei left.
• Because the limit order tries to sell whichever token the vault
• holds more of, the vault's holdings will have a tendency to get
• closer to a 1:1 balance. This enables it to continue providing
• liquidity without running out of inventory of either token, and
• achieves this without the need to swap directly on Uniswap and pay
• fees.
