Optimization.jl: A Unified Optimization Package

Optimization.jl seeks to bring together a variety of optimization packages, local and global, into one unified Julia interface. This enables a user to learn one package, and be able to use all the packages. Optimization.jl adds a few high-level features, such as integrating with automatic differentiation, to make its usage fairly simple for most cases, while allowing all the options in a single unified interface.
