Doug Cutting updated AVRO-872:
------------------------------

    Attachment: AVRO-872.patch

Here's a version where getTypes() returns Map<String,Schema>.  This implementation not very efficient since it creates new Map entries each time its called.  This could be optimized, either by defining and returning a Map implementation wrapping the Names instance, or by converting Names to be a Map<String,Schema> and returning it directly.  But I'm not sure that's worth the effort now, since this doesn't seem a likely performance bottleneck.
