save captured metrics to file
moved the fail whale to the utilities folder
moved time to the espruino folder, it is basically wrapping an espruino command
created an observer that will save the frequency that the quad loops over sensing and adjusting throttles
hooked in the loop frequency metric end to end
moved the scheduler to the utilities directory
moved watch to the utilities directory
moved the adjust throttles to a flight namespace
moved the pid and propeller to the flight namespace
added espruino gotchas so that I don’t get caught out again.
