Most recent updates (34):
 - added "alert" function between cycles
 - added "prompt" function between cycles, allows user imput which is returned in data JSON as prompt_rsp
 - added "note" which acts as an environmental variable, allows user input at beginning of end of measurement
 - for all user inputted text (ie "prompt" or "note"), char limit is 999, do not use any of the following: [ ] + " '
 - cleaned up unnecessary spaces in output data JSON
 - added ability to exit any delay (average, protocol, measurement, etc.) using -1+
 - added ability to exit a measurement (between protocols only, not inside a protocol) by using -1+-1+ (all at once, no delay)
 - still need to test 34 internally before moving out of _dev.
