Extracting and making use of ANEW tables

The ANEW (Affective Norms for English Words) is a dataset that puts a valence, or mood to words. Using this (all be it from 1999) data, we can derive the mood of a body of text, such as a Tweet - however first things first, lets get the data into a usable form and learn how we can make use of it.
