Code cleanup

[darrencl]

Ensure that the code has consistent style by using code formatter, such as JuliaFormatter.

Closes #203

[darrencl]

@tlienart Here's a draft PR to look at JuliaFormatter. I tested this on Constant.jl. If there's any other file you want me to test this with, kindly let me know! :)

[tlienart]

did you try playing with the parameters a bit? I like the idea that the formatter would just get "everything in the same style" (though it doesn't seem to like vertically aligning = signs which I find to sometimes help with readability (e.g. in metadata); this is a matter of personal preference though, same with the way it handles brackets).

I kind of wonder whether this is worth the effort. Generally we do want something close to it but also flexibility for whatever may (subjectively) help readability locally.

What do you think? (and thanks!)

@tlienart The file in this PR is generated from default setting, but here's the list of options that we can modify.

It seems that there is no option to align = vertically and I agree it's nice for metadata or something like that. With that said, we generally only want this in specific block of code and we can always skip the formatter for that block (See here).

Oh that makes sense, well then I'm happy for you to go ahead when you have the time, and use your judgment in terms of where it makes sense to leave the formatting as is, thanks a lot!

I'm closing this old PR to remove clutter. Feel free to re-open.
