* 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.
*

* @title GraphTokenLockWallet
* @notice This contract is built on top of the base GraphTokenLock functionality.
* It allows wallet beneficiaries to use the deposited funds to perform specific function calls
* on specific contracts.
*
* The idea is that supporters with locked tokens can participate in the protocol
* but disallow any release before the vesting/lock schedule.
* The beneficiary can issue authorized function calls to this contract that will
* get forwarded to a target contract. A target contract is any of our protocol contracts.
* The function calls allowed are queried to the GraphTokenLockManager, this way
* the same configuration can be shared for all the created lock wallet contracts.
*
* NOTE: Contracts used as target must have its function signatures checked to avoid collisions
* with any of this contract functions.
* Beneficiaries need to approve the use of the tokens to the protocol contracts. For convenience
* the maximum amount of tokens is authorized.
