Context.sol

This is a Solidity contract named 'Context' that provides information about the current execution context, including the transaction sender and its data. This contract is especially useful when dealing with GSN meta-transactions where the account sending and paying for execution may not be the actual sender. The contract contains two internal view functions '_msgSender' and '_msgData' that return the sender's address and the transaction's data respectively.
