 *
 * TIP: For a detailed writeup see our guide
 * https://forum.zeppelin.solutions/t/how-to-implement-erc20-supply-mechanisms/226[How

 * We have followed general OpenZeppelin Contracts guidelines: functions revert
 * instead returning `false` on failure. This behavior is nonetheless
 * conventional and does not conflict with the expectations of ERC20
 * applications.
 *
 * Additionally, an {Approval} event is emitted on calls to {transferFrom}.
 * This allows applications to reconstruct the allowance for all accounts just
 * by listening to said events. Other implementations of the EIP may not emit
 * these events, as it isn't required by the specification.
 *
 * Finally, the non-standard {decreaseAllowance} and {increaseAllowance}

/*
    This master chef is based on SUSHI's version with some adjustments:
     - Upgrade to pragma 0.8.7
     - therefore remove usage of SafeMath (built in overflow check for solidity > 8)
     - Merge sushi's master chef V1 & V2 (no usage of dummy pool)
     - remove withdraw function (without harvest) => requires the rewardDebt to be an signed int instead of uint which requires a lot of casting and has no real usecase for us
     - no dev emissions, but treasury emissions instead
     - treasury percentage is subtracted from emissions instead of added on top
     - update of emission rate with upper limit of 6 BEETS/block
     - more require checks in general
