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.
The Kotlin version of Astronomy Engine was using Java
classes like `Date` and `GregorianCalendar`.
Reworked the code to use a completely self-contained
representation of calendar date/time, just like the C version does.
Now Astronomy Engine does not depend on anything outside of
the Kotlin standard library. This should allow us to use
Astronomy Engine for Kotlin Native apps, Web Assembly, etc.
Updated Java demo to use the new method Time.fromMillisecondsSince1970.
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.
