Provides APIs for integrating application models with the workspace

## Package Specification

This package specifies the APIs in the Resources plug-in that are used to integrate application models with the workspace. This API introduces the notion of a `ResourceMapping` that defines the relationship between an application model object and a set of underlying resources, and a `ResourceTraversal` that describes the exact resources corresponding to a given application model object. The relationship between an application model and underlying resources can vary depending a context. This notion is captured by `ResourceMappingContext` and its subclasses.
