proposal to make some C++ object APIs more generic
--------------------------------------------------

                 Key: AVRO-59
                 URL: https://issues.apache.org/jira/browse/AVRO-59
             Project: Avro
          Issue Type: Improvement
          Components: c++
            Reporter: Scott Banachowski


This is a patch I made for the serializer.  In the original version, the Serializer object
has functions like putInt(), putLong(),..., i.e. each put* function has a different name.
 

This is not convenient for generic template code, because each type requires a different function
call.  I moved the Serializer code to a class called Writer, that has only putValue overridden
for each type, e.g. putValue(int32_t), putValue(int64_t), putValue(bool) etc.

Generic code, such as in AvroSerializer.hh can use the generic API.  To preserve the explicit
calls, Serializer still exists, but has become a thin wrapper for Writer.  The explicit calls
are still useful for when you don't want implicit conversion to accidentally choose the wrong
type.
