GoVader: Vader sentiment analysis in Go

This is a port of https://github.com/cjhutto/vaderSentiment from Python to Go.

There are tests which check it gives the same answers as the original package.

Usage:

import (
    "fmt"
    "github.com/jonreiter/govader"
)

analyzer := govader.NewSentimentIntensityAnalyzer()
sentiment := analyzer.PolarityScores("Usage is similar to all the other ports.")

fmt.Println("Compound score:", sentiment.Compound)
fmt.Println("Positive score:", sentiment.Positive)
fmt.Println("Neutral score:", sentiment.Neutral)
fmt.Println("Negative score:", sentiment.Negative)

A server wrapper is available in https://github.com/PIMPfiction/govader_backend.
