> Contribution groups allow service implementations that are closely linked together, to be created multiple times (using markers to identify them) with automatic dependency resolution. 
> e.g. service implementations OneImpl (implements One) and TwoImpl (implements Two) use eachother, then with markers red and blue, we get One@Red and One@Blue and Two@Red and Two@Blue. They will each have their own configurations (unmarked contributions go to both Red and Blue, but contributions marked Red will go to the One@Red and Two@Red services, etc.)
> This is applied to the hibernate and hibernate-core services, allowing multiple databases to be used without having to use spring services.
