This package is unregistered yet, so you should use dev version. To add master version switch julia to pkg mode by pressing ] and enter

pkg> add https://github.com/Arkoniak/StrayCopses.jl.git

Currently this is a toy project, so API can be unstable, very unfriendly and so on. There are two ideas that I want to try in this package

1. Push calculation speed as much as possible
2. Use it as a test-bed for various random forest techniques that currently are scattered in various papers and narrow implementations.
