/**
* @file ump_debug.h
*
* The file include several useful macros for debugging and printing.
* - UMP_PRINTF(...) Do not use this function: Will be included in Release builds.
* - UMP_DEBUG_TRACE() Prints current location in code.
* - UMP_DEBUG_PRINT(nr, (X) ) Prints the second argument if nr<=UMP_DEBUG_LEVEL.
* - UMP_DEBUG_TPRINT(nr, X ) Prints the source trace and second argument if nr<=UMP_DEBUG_LEVEL.
* - UMP_DEBUG_ERROR( (X) ) Prints an errortext, a source trace, and the given error message.
* - UMP_DEBUG_ASSERT(exp,(X)) If the asserted expr is false, the program will exit.
* - UMP_DEBUG_ASSERT_RANGE(x, min, max) Triggers if variable x is not between or equal to max and min.
* - UMP_DEBUG_ASSERT_LEQ(x, max) Triggers if variable x is not less than equal to max.
* - UMP_DEBUG_ASSERT_POINTER(pointer) Triggers if the pointer is a zero pointer.
* - UMP_DEBUG_CODE( X ) The code inside the macro is only copiled in Debug builds.
*
* The (X) means that you must add an extra parantese around the argumentlist.
*
* The printf function: UMP_PRINTF(...) is routed to _ump_sys_printf
*
* Suggested range for the DEBUG-LEVEL is [1:6] where
* [1:2] Is messages with highest priority, indicate possible errors.
* [3:4] Is messages with medium priority, output important variables.
* [5:6] Is messages with low priority, used during extensive debugging.
