// BtBinderFacade provides simple wrappers to call Binder apis.
// Each public function returns a tuple of the return type and an integer
// representing the pass/fail value of the function. The functions check to see
// if the API call is actually possible. If it is the function's tuple will
// contain the actual result and an integer that indicates the value passed. If
// the function is not possible then there will be a mock return value in the
// first position of the tuple and the second value in the tuple indicates the
// value failed. Therefore it is up to the function to decide whether the
// expected api call is actually possible before calling it.
//
// TODO(tturney): Instead of using an integer in the tuple to represent
// pass/fail, create a class that properly represents the result of the
// function.
