Add more 4-9 more goal examples, so that we have examples that cover all goal elements and contexts.

Per the QA report 2a. Examples should exist for every example context identified in the resource introduction and must, between them, show the use of every data element in the resource definition. Examples should include a mixture of "simple" and fully fleshed out "complex" scenarios. (Expect 5-10 examples/resource)
