Reading SentiLex file
Loading sentilex json file
We now need to take accented letters into account
Changed the way module.export is structured

By default, the english dictionary is used. Nevertheless, the user now has the option
to call sentiment.lang() and define which language he/she wants to use. Currently,
we support Enlgish and Portuguese.

// English
sentiment = require('sentiment');
var result = sentiment(string)

// Portuguese
sentiment = require('sentiment')().lang('pt');
var result = sentiment(string)
Added unit test
