-Eventually this will be a repository containing one or more simplified interfaces for expressing certain classes of POMDPs. The goal is for [POMDPs.jl]( https://github.com/JuliaPOMDP/POMDPs.jl) to act as a low level interface (like [MathProgBase](https://github.com/JuliaOpt/MathProgBase.jl)) and for the interface(s) defined here to act as concise and convenient high-level interface (like [JuMP](https://github.com/JuliaOpt/JuMP.jl) or [Convex](https://github.com/JuliaOpt/Convex.jl).

 Contributions of new interfaces for defining specific classes of problems are welcome!
