Doug Cutting resolved AVRO-1332.
--------------------------------

    Resolution: Fixed

Oops!  Sorry I missed those files.  (We should have automated csharp builds to catch mistakes like that...)

I just committed the missing files and the updated default handling.  Does this look better?

Thanks!

> The current implementations of the C# datum readers perform resolution of the reader and writer schema on every call to Read. In my tests this was causing it to perform poorly when reading a large number of records (slower than parsing the same data from delimited text files). It would be more efficient if the reader only needed to resolve the schemas once.
