Add installation script

[athityakumar]

Writing a shell script to install all the dependencies, would make deployment easier.

cd frontend && yarn
cd ../backend
pip3 install -r requirements.txt
python3 -m nltk.downloader all

@athityakumar are we using both python2 & python3 ?

[athityakumar]

I'm using python3 (3.6.1).

@ghostwriternr - Please don't tell me that the codebase is partly python2 and partly python3? 😢

[rudrasohan]

I'm just worried about the OpenCV part. People generally use OpenCV packaged with ROS which is in python2.7

[ghostwriternr]

I don't what we've been using so far, but we should stick to Python3.

[athityakumar]

Well, there is only so much that __future__ can quick-fix between python2 & python3. Quick-fixing dependencies between pip & pip3 is sadly beyond its scope. :trollface:

@rudrasohan - We definitely don't need ROS for our task, and I think OpenCV with python3 should work just fine. Though, can you confirm that?

[ghostwriternr]

Ohh yep. ROS isn't needed. (Source: I don't have ROS)
