Scala Native support

[david-bouyssie]

I would like to discuss here the possibility of building the library for Scala Native.
Do you see any clear obstacle?
Thanks.

In case anyone is interested in this issue, I have started a draft on my fork (commit ex0ns@1c7ca2a)

The main issue is the usage of java file in the repository (LineReader and SourceLineReader in the java/com/github/totoshi/csv folder),

In the current state, the build for the JVM should be exactly the same as before, however the build for scala native fails with a

I don't really know why we have java file in this repository ? We may be able to re-implement them in Scala for scala-native (keeping the original java file for the JVM only).

@tototoshi could you tell us what is the reason behind those java file ?

Thanks
