-------------------------------------

Sorry - I can create another patch with those extra tests. I'll get onto that.

> The Drill query engine rejects column aliases for aggregates or group by fields where the alias includes a dot.
> For example:
> {code}select count(*) as `test.field` from cp.`employee.json`;{code}
> throws an error with "Field references must be singular names."
> Having reviewed the code, I can't quite see a reason for it, and when using FieldReference.getWithQuotedRef instead in AggPrelBase, the issue is alleviated with no visible side effects.
> I'm sure there was a reason for this code in FieldReference, but I can't seem to work out why, and it seems entirely reasonable to allow a dot in a column alias.
