/**
* Sample WireComponents task.
*
* This sample shows how to use a subset of Tuscany to read contribution
* metadata, analyze and resolve contribution dependencies, read and resolve
* the artifacts that they contribute (in particular implementation artifacts,
* interfaces, composites, componentTypes etc.) and assembe and wire the
* deployable composites together in a composite model representing an SCA
* domain composite.
*
* The sample first reads the SCA metadata for three sample contributions,
* reads and resolve the artifacts contained in the contributions, includes all their
* deployable composites in a composite model representing an SCA domain, then
* uses a composite builder utility to assemble and wire the composites together.
* Finally it prints the resulting domain composite model.
