Rewrite some code comments to be more clear
Increase buffer overflow warning to WARNING log level.
Make code of daq functions nicer by adding return instead of nesting the whole function
API BEHAVIOUR CHANGE: remove daqClear() call from the DAQ readout functions.
The DAQ stays alive even if the full buffer is read out. Adding a daqClear()
function to daqStart() to clear all previously started DAQ sessions at startup.
Add comment to daqGetNDecoderErrors() function
daqStop() should return "true" if everything went fine...
