* @brief Shell commands to test a CongURE implementation
*
* This module requires an application defined `congure_impl.h` which defines
* the congure_snd_t extension of the CongURE implementation as
* @ref congure_test_snd_t and provides a function declaration
* @ref congure_test_snd_setup() setup said type. E.g.
*
* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ {.c}
* typedef congure_reno_snd_t congure_test_snd_t;
*
* void congure_test_snd_setup(congure_test_snd_t *c, int id);
* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
*
* All constants and initial values can then be set within the application
* specific definition of @ref congure_test_snd_setup().
