Accept other dict-like types

[yassineAlouini]

In the helper.py script, the get_score_dictionary function makes a type check for the input scores: if it is a dict, it will return the scores, otherwise, it will attempt to read from a hardcoded data folder.

This is fine of course but it would be more robust to have it accept other dict-like types. One such type is Collections.Counter. Also, it would be nice to make the data path not hardcoded.

Thanks in advance. :smiley_cat:

I just added support for lexicons within Shifterator: https://github.com/ryanjgallagher/shifterator/tree/master/shifterator/lexicons

If you upgrade via pip, then when you're doing something like a sentiment shift, you should just have to specify the name of a lexicon (the filename without the .tsv) and it'll load that lexicon automatically.

For example:

rs = rs.SentimentShift(reference=type2freq_ref, 
                       comparison=type2freq_comp,
                       sent_dict_ref='SocialSent-historical_1920', 
                       sent_dict_comp='SocialSent-historical_1970')

If you run into any trouble, let me know!
