@update
<> move the drivers' context into the trace session
<> add "special" constructor for a "pre-initialisation", usefull to move the
callgraph generation into its specific menu part.
@fix
<> when the TRACER_CALLGRAPH is not set, the callgraph was always generated. (fixed)
@update
<> Now, the tracer have it own world (a copy of gint world), so this allows the
tracer to be completely independent vis-à-vis the traced world. The world can
be analyzed with a menu (not implemented but noted in the TODO)
