/**
* @brief This macro is used to adapt ASSERT and CHECK macros such
* that they assert or a relation. If the relation is violated, the
* arguments to the comparision are converted to strings and included
* into the exception what and the log message.
*
* @attention be aware, that in case of an error, the two operands OP1
* and OP2 are evaluated THREE TIMES. I consider this a bug---to be
* fixed.
*
* for example: DIAGNOSTICS_RELATION(DIAGNOSTICS_AUDIT_ASSERT1,Test_Exception,min,<=,max);
*
* This macros is usually wrapped into other macros for the sake of succinctness.
