mango Scala module

[cjnolet]

There are a few things I think would be great for a Scala module.

We could implement implicit conversion functions/classes to do things like automatically call build() on a builder when the builder itself is being assigned to the object that it's building.

There are others, we should list them as we think of them. One of them is also for the JsonAttributeStore to be able to convert the boxed map objects to and from java and scala types automatically.
