/**

* The benefit of using this method instead of calling
* Query.toString directly is that it knows about the data
* types of each field, so any field which is encoded in a particularly
* complex way is still readable. The downside is that it only knows
* about built in Query types, and will not be able to format custom
* Query classes.
