Suggestions for quick things to try
___________________________________

- Run a MultiNest scan. 
  (Plotting the results will require some changes to WC_lite.pip)


- Try to abort a scan (ctrl-c and wait...) and afterwards resume it 
  safely by calling GAMBIT *without* the restart flag -r, i.e.
  
    ./gambit -f WC_lite.yaml 


- Use the GAMBIT diagnostics system to figure out which function
  calculates the b2sll log-likelihood. (Commented out in WC_lite.yaml)
  
  Take a look at this function in FlavBit/src/FlavBit.cpp  
  (A fairly clean illustration of a GAMBIT module function.)
