Debug Support: You can use body_begin() together with body_end() ! to enable debug, this means you are ale to set break ! points and single-step into those states. ! ! Example: 
  vsf_fsm_begin()
      vsf_state(xxxxx,
the range no debug is allowed )

vsf_state(xxxxx){ the range you can debug with }
