it0000: The simplest of builds. We have one application class and one test
        class. There are no resources, no source generation, no resource
        generation and a the super model is employed to provide the build
        information.

it0001: Build upon it0000 we add an application resource that is packaged
        up in the resultant JAR.

- generated sources
- generated resources from sources
- generated resources from generated sources
- filtered resources
- build that requires a plugin download
- transitive dependencies
- goal attainment not requiring depedency resolution
- goal attainment where a POM is not required: this is a case where
  we are using mgen to create new applications and project structures
  which is used by the m2 geronimo plugin and tools like the "setup"
  goal which brings a project to life from scratch using something like:
  m2 --setup xstream --version 1.0

- write a small program to generate a massively nested build
  which which use the reactor and inheritence. we need to have
  integration tests that go far beyond what the average user
  would ever setup.
