This example starts the TemperatureConverter activity then type '123' into the 'Celsius' field.
Then a ViewClient is created to obtain the view dump and the current values of the views with
id/celsius and id/fahrenheit are obtained and the conversion printed to stdout.
Finally, the fields are obtained by using their tags and again, conversion printed to stdout.

If --localViewServer is passed in the command line then LocalViewServer provided by
TemperatureConverter is used. This is very useful when the device is secure and ViewServer
cannot be started.
