Ref #48 (comment)
- Rename LearnBase.jl ➡️ LearnAPI.jl (similar to StatsAPI.jl and DataAPI.jl)
- Create MLBase.jl as an umbrella over MLDataPattern.jl, MLLabelUtils.jl, LossFunctions.jl, and PenaltyFunctions.jl
For (2), do we want an umbrella package or consolidation of code? Right now, I prefer the former to maintain small dependencies for people who need them. But maybe after those packages get cleaned up, they will be trivially small.
