* \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.
