Passes the device's current position. When called, it returns the initial Position
object, which
describes the device's current location.
If the attempt is successful, the successCallback
method is called
periodically, depending on the settings defined in the options
parameter, with a new Position
object. If the attempt fails, the
errorCallback
method is invoked with a new PositionError
object, reflecting the reason for the failure.
The method returns and then asynchronously attempts to obtain the current location of the device.
