Implemented Astronomy.siderealTime() in Kotlin.
Updated all languages' unit tests for sidereal time
to verify exact conformity between them, rather than
to an externally derived value. I wanted to make
sure all languages, including Kotlin, are calculating
the exact same value.
I don't need an external authoritative test for
sidereal time, because it will be indirectly tested
through its involvement in thousands of other calculations
that depend on it. I just need a quick sanity check
before implementing those other things that depend on it.
Ported the following types to the Kotlin code:
GlobalSolarEclipseInfo
EclipseEvent
LocalSolarEclipseInfo
TransitInfo
ShadowInfo
IllumInfo
AxisInfo
NodeEventKind
NodeEventInfo
Made some wording fixes in the documentation for the
other languages.
I didn't realize Dokka doesn't clean up its output directory
before writing documentation files. This caused stale documentation
to still exist from previous builds. The result was a failed
unit test because the generated documentation did not match
what was checked into git.
In general, I want to make sure that builds I run on my development
system exactly match what GitHub Actions does on its cloud platform.
So before running the `gradlew` build step, I delete the entire
directory source/kotlin/build. This directory is always absent
on GitHub Actions, which makes my local build better match the
remote build.
Merge a custom Markdown prefix with documentation
generated by dokka from Kotlin source code into
the published GitHub page. See the new script:
generate/kotlindoc/format_kotlin_doc.py
The result is not yet quite what I want, but it
is much better than nothing.
Things to improve:
The `object Astronomy` link should not be hidden
in the middle of the other types. It should be
expanded and promoted to the top level.
