Suspendable defines rules for Runnable
implementations whose instances process could be suspended.
Implementers should consider the possibility for the user of the class
to suspend or not the operation, if the operation could be suspended,
the implementer should create a Suspendable class.
More formally, an operation is suspendable if and only if the operation could
be paused(stopped) and resumed(re-started) without breaking the state of the
process. For example, a loading process could be stopped, but it couldn't
be suspended, when a file loading is stopped there's no possibility to restart
it at the point it was stopped. In that logic, the only way to reset the state
of a suspendable operation is to call the reset method defined
in this interface.
Implementing the Suspendable interface doesn't require anything
regarding the time outflow approach. The only requirements concerned the suspendable
nature of the process.
Note : There's no restriction concerning class which would implements both Suspendable
and Cancelable interfaces.

| Player version: | Flash Player 9.0 |
| Language version: | ActionScript 3.0 |
Resets the state of this object. The state of an operation
could be reset at any time, whether it be running or stopped.
Concret implementation, which not support the reset
method, can choose to throw an exception or to simply ignore the
call.
UnsupportedOperationException — The reset
method is not supported by this implementation

| start | () | method |
public function start():void
| Player version: | Flash Player 9.0 |
| Language version: | ActionScript 3.0 |
Starts the operation of this suspendable operation.
If a call to the start method is done
while the operation is playing, concret class must
ignore it.
| stop | () | method |
public function stop():void
| Player version: | Flash Player 9.0 |
| Language version: | ActionScript 3.0 |
Stops the operation in process. If a call to the
stop method is done whereas this operation
is already stopped, concret class must ignore it.
