AirdropModule

Module that enables managers to absorb tokens sent to the SetToken into the token's positions. With each SetToken, managers are able to specify 1) the airdrops they want to include, 2) an airdrop fee recipient, 3) airdrop fee, and 4) whether all users are allowed to trigger an airdrop.
