add module for tweet scraping and word cloud generation

[mratanusarkar]

moving the code from the ipynb into a python module. but, still need to look for the possibilities for the following:

• [ ] breaking down the code into even smaller modules and functions.
• [ ] look for a more generalized naming scheme.
• [ ] some functions feel hardcoded and could be further generalized.
• [ ] reduce file content of scraper.py
• [ ] fix issue with the word_cloud package
• [x] add documentation

Fixing the word_cloud package issue would also close https://github.com/mratanusarkar/twitter-sentiment-analysis/issues/6

5/6 unfinished tasks will be taken up once the issue #6 is resolved.
