Refactor code of TimeLine.java

[vibhcool]

• Issue type: Feature request

At present

Timeline iterates MessageEntry(super class of TwitterTweet object that stores tweet's data) objects.

Issue

MessageEntry is specialized for TwitterTweet, so it can't be used for other scrapers. So Post class is used to solve the purpose. All Scraper objects store different type of data, so Timeline can't be used to iterate the objects of other scrapers. For that more generalized Post objects shall be iterated instead of MessageEntry object.

I want to propose to refractor the Timeline.java code to be able to iterate Posts objects.

EDIT 1: Added more explaination
