* period, or having an emergency switch for freezing all token transfers in the
* event of a large bug.
*
* IMPORTANT: This contract does not include public pause and unpause functions. In
* addition to inheriting this contract, you must define both functions, invoking the
* {Pausable-_pause} and {Pausable-_unpause} internal functions, with appropriate
* access control, e.g. using {AccessControl} or {Ownable}. Not doing so will
* make the contract pause mechanism of the contract unreachable, and thus unusable.
*
* _Available since v3.1._
