Generic interface for the [Stochastic Dual Dynamic Programming (SDDP) algorithm](http://www.optimization-online.org/DB_FILE/2009/12/2509.pdf) as well as a generic implementation.
The problem can either be provided using the [StructJuMP](https://github.com/joehuchette/StructJuMP.jl) modeling interface or using a lower level interface.
