Repackage this as Neptune.jl

For the general repackaging (first milestone) here's what needs to be done.

[x] Rename this repo (to Neptune.jl)
[x] Merge the no-analysis branch with master
[x] Update the Project.toml(Name, UUID etc.)
[x] Add your name to the LICENSE (since we have forked the exact same license, there shouldn't be any problems with the MIT license)
