Main differences with last major release:

 * Tweet objects do not store all the values as str anymore. The most used
   fields are now attempted to cast to their type on initialization. These
   improvements were added on the last versions of 0.5.x
 * Tests have been added that cover most of the code in tweets.py and utils.py.
   In the next versions probably even more will be added.

* Code from tweet_model.py now divided in two source files: tweet.py
  (containing the Tweet class) and utils.py (which contains the rest of the
  utilities to instantiate Tweet objects from CSVs, return a mini-dict with
  partial information of a Tweet, etc.)
* Added two new fields to the Tweet class: "polarity" and "trtext", which are
  not part of the original Tweeter tweets, but needed in other project.
* Added setter methods for "polarity" and "trtext", which will be probably now
  set at instantiation time but afterwards

Added functions that allow to get dictionaries representing a subset of the Tweet object information

Since the last release the main improvements have been:

 * Raise a custom exception instead of sysexiting when confronted with a wrong
 CSV file.
 * Change prints for logger messages.
 * Modularize the "get_tweets_from_csv" dividing it into 3 functions to
 provide more isolated functions. Now this function makes use of
 "get_tweet_from_csv_line", which returns a single Tweet object when
 provided with two lists representing the contents of a CSV header and
 one of its entries. There is also a "raw" alternative of that
 function, which works with raw lines and converts them to lists to then
 call the "non-raw" version.

Pretty stable release with the basic intended functionality
