Fetching user timeline tweets

[Mira-Alf]

• Introduced two new command line options u for userId and n for number of tweets(default value 10)
• If instead of the id, the u option is provided, then user's recent tweets are fetched
• Lots of testing needs to be done for how the tweets and their replies are displayed - I am ignoring retweets or replies to other users or tweets having any user mentions for now. These can be added down the road if necessary - any PDF structure change necessary needs to be accomplished by creating a separate template
• richRendering was causing some weird bugs - I have tried my best to fix them but puru needs to take a look at the changes to see if they are correct.
• Since the API endpoint used is a search endpoint only tweets made by the user in the last 7 days will be displayed. How to handle no tweets scenario??
