Using GIT with BitBucket (or any other remote repository)

It is quite simple. Follow this link to install and setup GIT:  https://confluence.atlassian.com/display/BITBUCKET/Bitbucket+101 Do not create a new repository in BitBucket, as we already have couple of repositories. Do your operations on any of the two existing repositories. How to use the GIT UI: After cloning ‘web-app’ repository I get the ‘web-app’ folder on my machine. Initially it is empty since there is no source code. I added a file ‘Read Me.txt’ If I right-click on the file and select ‘Git GUI’.

It aims to retrieve all the search results (tweets) and hence has to make multiple calls to REST API, for which it uses max_id (explained later).

You can set it to true if you want. max_id: Since we want more than 100 tweets, we are invoking the API multiple times and giving the id of last tweet returned in previous invocation as 'max_id' and asking Twitter to give 100 tweets prior to this tweet.  e.g. First call ret
