Alchemix UniV2 50/50 LP to Balancer 80/20 LP Migrator

About

Migrator.sol facilitates migrating UniV2 LPs to an 80/20 Balancer LP with the option to deposit directly into an Aura pool.

• LP: UniV2 LP Token
• BPT: 20WETH-80TOKEN Balancer Pool Token
• auraBPT: 20WETH-80TOKEN Aura Deposit Pool
• See MigrationCalcs.sol for the calculations that need to be made and passed into migrate()
• The calculations or output of getMigrationParams() should be used as values for MigrationParams in IMigrator.sol
• The Migrator will unwrap the UniV2 LP tokens, rebalance the 50/50 TOKEN/WETH balance to an 80/20 TOKEN/WETH balance by swapping extra WETH for TOKEN, deposit the rebalanced 80/20 TOKEN/WETH amount into a Balancer pool, and either deposit the newly minted BPT tokens into an Aura pool sending msg.sender auraBPT, or transfer the BPT directly to the msg.sender
