Cleanup repository

[hohwille]

Great to see that you did a OASP4J demo in Kotlin and thanks for that. I am also looking at Kotlin with increasing interest.

However, I wanted to give some feedback for improvements:

• you should have a .gitignore to prevent comitting generated files. See https://github.com/oasp/oasp4j/blob/develop/.gitignore
• as you had not .gitignore in place you comitted and pushed a lot of generate stuff like .settings and especially target folders what is heavily discouraged and should be deleted.

Here is an incomplete list of such files and folders:

• https://github.com/oasp/oasp4j-sample-kotlin/tree/master/server/target
• https://github.com/oasp/oasp4j-sample-kotlin/tree/master/server/.settings
• https://github.com/oasp/oasp4j-sample-kotlin/blob/master/server/.project
• https://github.com/oasp/oasp4j-sample-kotlin/tree/master/core/.settings
• https://github.com/oasp/oasp4j-sample-kotlin/blob/master/core/.project
• https://github.com/oasp/oasp4j-sample-kotlin/tree/master/core/target

BTW: The recommended way is to start such repositories on https://github.com/oasp-forge/ instead of https://github.com/oasp/. oasp-forge is for experimental stuff while oasp should contain "production-ready" projects (whoever created this repo [for you]). My intention is not to blame, just to let know...
