Enable audio communication via a Bluetooth SCO link

####Create a SCO link

BluetoothSco.start(function() {
    // success callback
}, function() {
    // error callback
}, {enablePlayback: true});

The last argument is optional. If enablePlayback is set false (or not at all), the link is used to route audio from the Bluetooth headset to the phone (one-way link). If set true as above, a two-way link is created.

####Remove SCO link

BluetoothSco.start(function() {
    // success callback
}, function() {
    // error callback
});

The plugin will not switch device's Bluetooth on or off, or try to pair with a headset. You have to do that in some other part of your code.
