/*
* \brief Wrapper of a nitpicker session
* \author Norman Feske
* \date 2014-10-01
*
* This utility is intended to reduce repetitive boiler-plate code of
* components that intercept the nitpicker session interface. By default,
* all RPC function calls are forwarded to the wrapped session. So the
* implementations have to override only those functions that need
* customizations.
