/**
* \file
*
* \par Purpose
*
* Standard output methods for reporting debug information, warnings and
* errors, which can be easily be turned on/off.
*
* \par Usage
* -# Initialize the DBGU using TRACE_CONFIGURE() if you intend to eventually
* disable ALL traces; otherwise use DBGU_Configure().
* -# Uses the TRACE_DEBUG(), TRACE_INFO(), TRACE_WARNING(), TRACE_ERROR()
* TRACE_FATAL() macros to output traces throughout the program.
* -# Each type of trace has a level : Debug 5, Info 4, Warning 3, Error 2
* and Fatal 1. Disable a group of traces by changing the value of
* TRACE_LEVEL during compilation; traces with a level bigger than TRACE_LEVEL
* are not generated. To generate no trace, use the reserved value 0.
* -# Trace disabling can be static or dynamic. If dynamic disabling is selected
* the trace level can be modified in runtime. If static disabling is selected
* the disabled traces are not compiled.
*
* \par traceLevels Trace level description
* -# TRACE_DEBUG (5): Traces whose only purpose is for debugging the program,
* and which do not produce meaningful information otherwise.
* -# TRACE_INFO (4): Informational trace about the program execution. Should
* enable the user to see the execution flow.
* -# TRACE_WARNING (3): Indicates that a minor error has happened. In most case
* it can be discarded safely; it may even be expected.
* -# TRACE_ERROR (2): Indicates an error which may not stop the program execution,
* but which indicates there is a problem with the code.
* -# TRACE_FATAL (1): Indicates a major error which prevents the program from going
* any further.
