Used IntelliJ IDEA's linter to perform code cleanup.
There were unused variables, `var` that could be replaced with `val`,
and other minor code style issues.
While doing this, I also discovered that a lot of documentation
links were broken. The fix is to stop intenting the text after
a `@param`.
I found that there were a bunch of lingering 'jvm'
tags in the generated markdown documentation.
Got rid of them with another change to format_kotlin_doc.py.
The dokkaGfm tool has a few oddities I don't like.
I updated my format_kotlin_doc.py script to work around
a couple of them:
1. Strip out all the noisy [jvm] tags it puts everywhere.
2. Remove the unhelpful and incorrect `Properties` sections
it adds to all my enum classes and enum members.
I will come back and address other issues later.
Renamed AstroTime to Time.
Renamed AstroVector to Vector.
For some reason this breaks the Java demo build.
I'm pushing the broken build anyway to see if
ebraminio can help me fix it.
