Migrate to multiplatform

[Dominaezzz]

So I've setup a multiplatform project with only a JVM target for now.
I expect we'll gradually move components to the common source set .... until we can't.
Then we'll look at viable abstractions.

There's one tiny gotcha. The play button IntelliJ offers when looking at a sample file won't work anymore because of a bug in IntelliJ (about resource handling) we discussed.
So I've created a gradle task for each sample to run them.

Will check it out!

First the IDE was not able to find any three.kt classes. Everything red. This I fixed by selecting the "use separate modules per source sets" option. However, I can't run the examples either through run file or using the tasks you made. I get Error: Could not find or load main class ...

I could push #29 forward to (partly) resolve the resource issue

Hmm, I did gradle clean then gradle runBasicSample and it still works.
Can I see the full output of the two commands?

Task :examples:runBasicExample FAILED
Error: Could not find or load main class info\laht\threekt\BasicExample
Caused by: java.lang.NoClassDefFoundError: info/laht/threekt/BasicExample (wrong name: info\laht\threekt\BasicExample)
Error: Could not find or load main class info\laht\threekt\BasicExample



Caused by: java.lang.NoClassDefFoundError: info/laht/threekt/BasicExample (wrong name: info\laht\threekt\BasicExample)

Running with --stacktrace crashes. Dunno if that's related.

Oh, you're not on Linux. I made a terrible assumption about path separators. 😅

[markaren]

That was better!

With the README update I pushed I think we can merge this and slowly improve it.
