Multiple New Functionalities

[retailos]

TL;DR

Added the following functionalities :

• Support for extending AFINN-111 with custom words
• Added support for phrase-words ( ex : "don't like" )

Added the follow break functionality :

• Transformed Sentiment Analysis to a class

Long Version

Now instead of using directly the library, the user makes a new Object :

var sentimentAnalysisLib = require('sentiment-analysis');
var sentimentAnalysis = new sentimentAnalysisLib();

sentimentAnalysis.analyseSentence('Dinosaurs are awesome!'); // +0.4

The user now can use custom words ( this is why the library now is a class )

var sentimentAnalysisLib = require('sentiment-analysis');
var sentimentAnalysis = new sentimentAnalysisLib({
    customWordsFile : 'myCustomAfinn.json'
});

sentimentAnalysis.analyseSentence('Dinosaurs are awesome!');

var sentimentAnalysisLib = require('sentiment-analysis');
var sentimentAnalysis = new sentimentAnalysisLib({
    customWords : {
        dinosaurs : -4
    }
});

sentimentAnalysis.analyseSentence('Dinosaurs are awesome!'); // 0

And this improvement/bug fix, now the library can handle words composed by multiple words ( I call them phrase-words ).
In the AFINN-111.json there're 15

1. "can't stand"
2. "cashing in"
3. "cool stuff"
4. "does not work"
5. "dont like"
6. "fed up"
7. "green wash"
8. "green washing"
9. "messing up"
10. "no fun"
11. "not good"
12. "not working"
13. "right direction"
14. "screwed up"
15. "some kind"
