Dev: 
Katana.jl is a MathProgBase solver for Convex NonLinearPrograms (NLPs). Katana.jl solves NLPs via the Extended Cutting-Plane (ECP) method, which combines an Linear Programming solver with a cutting-plane generator to solve Convex NLPs. Katana.jl is well suited for large-scale Convex NLPs where most of the constraints are linear and the nonlinear constraints are sparse.
