Jaccard similarity document manager

This package uses Jaccard similarity with bag of words to find similarities between passed in contents and a json file.

There are two useful functions:

save(filename, docID, contents) ===> takes in the json filename, an id for the document you want to save,

and the contents of the document in a string. The function adds on the docID and contents to filename, and if filename doesn’t exist, it creates a new file and inserts the passed in contents.

def getSimilarities(filename, docID, contents, threshold) ===> takes in the filename of all the documents to

to compare to, docID of the document you want to find similarities for, the contents of the document, a similarity threshold between 0 and 1 inclusive. The function returns a list of (similarity, docID) in descending order of all documents whose similarities are above or equal to the threshold.
