Port JavaRosa tests, ignore ones that fail

[lognaturel]

Skip:

• ones that relate to functionality that's not intended to be supported yet (e.g. events and actions)
• ones that are tightly-coupled to the JavaRosa internal representation

Put in separate test package so we're not inheriting all of the test structures from JR

Maybe wire up something to show alignment level with JR

How can we establish a link between the tests between the two libraries?

My general feeling while going over #26 is that the smoke tests and DAG tests are the most interesting. There are a few other valuable ones here and there but overall I feel like the test quality is not all that high.
