This commit makes significant effort towards refactoring the repository so that it is in a cleaner and more consistent state going forward. Since we are now explicitly expecting multiple languages to be used for OpenUxAS, we have reorganized `src` accordingly. Likewise, we have reorganized `tests`. This is a candidate for the rebaseline of afrl-rq/OpenUxAS.
