/**
* This class creates artifacts to be used for testing purposes. It can optionally create actual files on the local disk
* for things like copying. It can create these files as archives with named files inside to be used for testing things
* like unpack. Also provided are some utility methods to quickly get a set of artifacts distinguished by various things
* like group,artifact,type,scope, etc It was originally developed for the dependency plugin, but can be useful in other
* plugins that need to simulate artifacts for unit tests.
