* @title Enoki Geyser
* @dev A smart-contract based mechanism to distribute tokens over time, inspired loosely by

* Distribution tokens are added to a locked pool in the contract and become unlocked over time
* according to a once-configurable unlock schedule. Once unlocked, they are available to be
* claimed by users.
*
* A user may deposit tokens to accrue ownership share over the unlocked pool. This owner share
* is a function of the number of tokens deposited as well as the length of time deposited.
* Specifically, a user's share of the currently-unlocked pool equals their "deposit-seconds"
* divided by the global "deposit-seconds". This aligns the new token distribution with long
* term supporters of the project, addressing one of the major drawbacks of simple airdrops.

* of returning `false` on failure. This behavior is nonetheless conventional
* and does not conflict with the expectations of ERC20 applications.

* 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}
