DEV tools: Script to automate creation of example code for an IC

__1. Created a new folder `/dev/`__
__2. Added `IC_example_code_maker.py`- a script to automate the process of making an example code for an IC__


* Takes IC No. as Input
* Scrapes the tests.py file for the sample input case
* uses `exec` to check if IC present in the code base.
* Extensively uses `format` to generate the code from a template code.
* The synthesized code is run to verify the integrity.
* produces an output ICNO.py in the dev folder . Has to be manually moved inside example.py
MOTIVATION: Saves a lot of dev time.
