**Pausable** - version: 0.1.12

Contract module which allows children to implement an emergency stop mechanism that can be triggered by an authorized account.

* This module is used through inheritance. It will make available the modifiers `whenNotPaused` and `whenPaused`, which can be applied to the functions of your contract. Note that they will not be pausable by simply including this module, only once the modifiers are put in place.
