Show HN: Keigen – A Kotlin/Android lib for matrix math using C++ Eigen

I created this library first and foremost because I couldn't find a simple arbitrary matrix math implementation for Android to use in a work related project (well, one fitting my requirements). I kind of drifted along and expanded the library to support all numeric types in Kotlin - it's quite simple to extend the supported matrix operations to whatever functionality in Eigen one wants :)

I'm still learning C++, so comments on the .cpp stuff are appreciated.
