-/* Class DebugTracer
- *  A code instrumentation utility
- * 
- * This object adds a function name or methodname/object instance 
- * to a stack on construction, and removes it on destruvtion. It 
- * can therefore be used at the start of functions to trace entry, exit
- * and the call graph/stack.
- *
- * Wrapped in macros and with altered implementations, the same instrumentation can:
- *  - be #defined away to nothing
- *  - provide the call stack on encountering an error
- *  - trace the runtime call graph (for the whole program run, or programatically on/off) 
- *
- *
- * Example
- *
- * Function example
- * > void foo(int x) { FUNCTION("foo");
- * >    // normal code
- *
- * Class method example
- * > void Foo::bar(int x) { METHOD("bar");
- * >     // normal code
