move paper source to separate repo

[conradsnicta]

The paper sources don't serve a directly useful purpose to the users of the software. Having a single pdf would be more useful (ie. it would be immediately viewable).

It would be good to clean this up and move the sources to a separate repo, in similar vein to the joss_paper for mlpack. As an added bonus, the modified arxiv version of the paper can be kept in the same repo.

(PS. I'm happy to do the actual moving / cleanup / etc.)

Sounds good to me, and as long as the paper and the potential joss paper is in the same repo as the main code we are fine (openjournals/joss-reviews#703 (comment)).

I created the empty repo https://github.com/mlpack/ensmallen_paper ; if you want to move the paper sources to there that sounds good to me. :)

Thanks! Now the sources are all in that repository.
