/**
 *  \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.
