Ownable
Contract module which provides a basic access control mechanism, where
there is an account (an owner) that can be granted exclusive access to
specific functions.
This module is used through inheritance. It will make available the modifier
onlyOwner
, which can be applied to your functions to restrict their use to
the owner.
