given sampling rate. This is basically using an iterator within the board class. Updated the util class so that the Iterator can also be stopped and added a flag. Added join to board so that it waits till the Treads terminates. Updated analog_realtime_scope.py which no longer needs to refer to util and calls the new sampling method in the board class.
New minor version number b/c of new features.

replaced with getfullargspec as suggested by @mdickers47 in #13
The com port is used by internal devices by HP or by bluetooth adapters which are then wrongly detected.
This has been suggested by @kdickie59 in #14 I cannot test it as it's fine on my RPI3 with the Uno but hopfully helps!

Thanks @Rotule666 for spotting this quite lax coding there. I've further improved it by adding a proper default behaviour in case the function letter is unknown or misspelt.
Some users just don't read the README, do some polling instead of using callbacks and then fire off an issue (#16). To prevent wasting my time the library now does a hard exception if somebody tries polling. This then recommends pyfirmata1.
@AlboProgrammer reported that the description string no longer contains "USB" but now the make of the Arduino. I've added this to the autodetect.

How to do that ? I didn't see any instructions on the web how I can do that. I'm trying to read the value of the distance sensor (Ultrasonic) from the echo_pin(PWM) I tried many many things but not success. He re in my code I was expecting to read it from the analog port 0 but I have many values that doesn't help me.
A help would be greatly appreciated. Thanks in advance.
