* This is a proxy contract.

* The implementation address must be located in a unique storage slot of the proxy contract.
* The upgrade logic must be located in the implementation contract.
* Special lock implementation address slot is produced by hashing the "eip1967.proxy.implementation"
* string in order to make the slot unique.
* The fallback() implementation for all the delegatecall-s is inspired by the Gnosis Safe set of contracts.
