/**

* @dev Provides information about the current execution context, including the

|
* sender of the transaction and its data. While these are generally available
|
|
* via msg.sender and msg.data, they should not be accessed in such a direct
|
|

|
|
* paying for execution may not be the actual sender (as far as an application
|
|
* is concerned).
|

|
|
* This contract is only required for intermediate, library-like contracts.
