A tracer object is the default interface to libcsdbg for the instrumentation functions and for the library user.
The public interface of the class is used by the instrumentation functions to create a call stack simulation for each executing thread. The library user can use the interface to produce and output traces for exceptions or for threads. The constructors of the class are protected so there is no way for the library user to instantiate a tracer object. The library constructor (on_lib_load) creates a global static tracer object to be used as interface to the library facilities. All public methods are thread safe
