OSCAR-code/oscar/SleepLib/loader_plugins/sleepstyle_loader.cpp
Guy Scharf 9f4cd79b3d SleepStyle loader now shows high resolution leak rate 
Loader calculates leak rate from mask pressure and does usual linear interpolation for leak rate for the pressure
  Calculation of CPAP_Leak is now done in the loader rather than in calcs.cpp
