   8 core_profiler.h:
   9    Lua version independent profiler interface.
  10    Responsible for handling the "enter function" and "leave function" events
  11    and for writing the log file.
  12
  13 Design (using the Lua callhook mechanism) :
  14    'lprofP_init_core_profiler' set up the profile service
  15    'lprofP_callhookIN'         called whenever Lua enters a function
  16    'lprofP_callhookOUT'        called whenever Lua leaves a function
