An abstraction of a network of wired objects. We needed our own, since Spring's BeanDefinition's don't work well with SpringTemplate, and because we need additional information not provided by BeanDefinitions. Apart from that, having a dedicated abstraction allows us to pull the configuration from other sources as well.

The {@link me.springframework.di.Instance Instance} models the definition of an object instance. Instances are configured through constructor arguments or property setters. The {@link me.springframework.di.Instance Instance} provides access to the configuration.

Property setters and constructor arguments are both {@link me.springframework.di.Sink Sinks}. That is, they can be connected to {@link me.springframework.di.Source Sources}. There are different types of sources. The source can be an anonymous instance, a reference to a named instance, a list of objects, or just the String representation of a value.
