Minor: Kotlin classes is compiled by pre-release version of kotlin and cannot be used by this version of compiler on 0.1.0

[Tradunsky]

When adding the artifact:0.1.0 from README file it has been compiled with kotlin pre release version and it leads to unexpected compilation errors when start using it on LATEST stable kotlin stdlib.

Probably it is not that straightforward to fix if 0.1.0 is in use within pre-release kotlin, if not - updating artifactory version 0.1.0 with release version of kotlin might be an option.

However, 0.1.1 fixes this situation. So, another option is update README with the latest version of the artifact
