About

This RewardManager allows to use deposit_reward_token() only on a preset of gauges provided on contract creation.

The manager can decide on the time and on the size of the reward, but has no access to funds anytime.

If set, a RecoveryGauge can be used to send back funds to a RecoveryAddress
