Linux : Virtual device creation and routing microphone audio via a python script

[arushsharma24]

Created a folder 'linux' which contains the following files:-

1. dynopii.sh : a shell script to create a virtual device named "dynopii" if it does not exist already, and stream microphone audio input into it.
2. a README.md on how to use the script

Update:
Now instead of a shell script, we have a python script (as originally planned for this project) which should fulfill all requirements on a linux system.
Commit : 619e3dd adds

1. dynopii.py : A python script that pipes audio from arecord to aplay, and this recorded audio can be further processed if so desired. Also runs the scripts dynopii.sh and close.sh
2. dynopii.sh : Creates the null-sink-module (basically our virtual device) named dynopii and opens pavucontrol.
3. close.sh : Closes the playback, the virtual device and the script. Is run automatically when the python script dynopii.py is quit using Ctrl-C.

Commit f7e9600 updates README accordingly

Update :
Included the code of all the shell scripts into the python file so there is no extra file (in c59265a and 598ddad), everything bundled inside the single dynopii.py file.
Also removed the superfluous lines as suggested from the readme as well. (fc2fe7f)

Thank you for reviewing and hope you can give this a look again whenever possible :)
