// Description:
// __ACTION_INFO_BEGIN__ 
// [Action Name]
// StartWatchers
// [Action Parameters]
// RProcess watcher <output-completion>:In case of EKA2 and EKA1 on hardware, output the process that started the watchers.
// If watchers are already running, this output parameter will not be returned
// or 
// RThread watcher  <output-completion>:In case of EKA1 on emulator, output the thread that started the watchers.
// If watchers are already running, this output parameter will not be returned
// TBool Started <output-completion>  : For all the cases, output ETrue if the watchers were created
// by the process or thread in this action, otherwise output EFalse
// [Action Description]
// If the watchers are not running, starts the watchers.  Watchers are started
// in their own process for EKA2 and EKA1 on the  hardware and in their own thread 
// for EKA1 on emulator.  The action waits for the watchers to start before completing.
// At the end of the test case, the watchers are stopped if they were created
// by the action.  If they were not created by the action, then the watchers 
// are not stopped.
// [APIs Used]
// None
// __ACTION_INFO_END__
//
