need better convenicence for MoArray, need wider expansion for * in output schemas

We can support the workflow of an author creating a normal Java/Groovy list, then inserting it into the variable bindinds via MoArray by adding another newArray(...) variant that takes an existing list.

We can allow a wider expansion of * in output schemas by replicating allowing more than a single "example output element". All of the example elements would be replicated per iteration of the * value.
