Configuring StructureMap in ASP.NET WebAPI

Last week I started to work in project with WebAPI and first thing what I noticed was improper usage of StructureMap as IoC container. I googled for StructureMap configuration in WebAPI, but couldn't find good solution. But, I found great tutorial how to inject dependencies into WebAPI controllers and do dependency injection with Unity IoC container: Using the Web API Dependency Resolver.
