/**
 * Responsible for building tooling models to return to the tooling API client.
 *
 * The {@link #buildAll(String, Project)} method is called to create a model for a given project. The model is serialized to the client process and passed
 * to the client application.
 *
 * The model object is adapted to the Java type that is used by the client by generating a view, or wrapper object, over the model object.
 * The model object does not need to implement the client Java type, but it does need to have the same structure as the client type.
 * This means that the model object should have the same properties and methods as those defined on the client type. The tooling API deals with
 * missing properties and methods, to allow evolution of the models. It will also adapt the values returned by the methods of the model object to the
 * types used by the client.
 * 
 *
 * Although it is not enforced, the model object should be immutable, as the tooling API will do some caching and other performance optimizations on the
 * assumption that the model is effectively immutable. The tooling API does not make any guarantees about how the client application will use the model object.
 *
 * Plugins can register their own tooling model builder implementations using {@link ToolingModelBuilderRegistry}.
