Moved the variables that define the dataset locations to before use of the paths. Updated the docs a bit.
Have fixed and tidied up the query to return the similarity between two users. Have implemented a quick version so that I don't have to wait for the full dataset to be processed.
Wrote a test query for the similarity query. It takes a really long time so not something to run during the meet up!
Updated the README to get it closer to being useable.
