Configure()

The function 'configure' is called whenever a module gets active, i.e. it becomes part of an active branch. It is not called again if the branch changes, but the modules is remains active.

In 'configure' the entire configuration as specified by the user in the module should be sent to the instrument. It is important that the configuration is not sent in initialize because it might change later again, for example if a second module connects to the same instrument in another branch where a completely new configuration is needed.
