Detailed Description

Root streamer that calls our converters when reading in non-split mode.

When we read objects with a converter in non-split mode, we get root to call the converter by installing a custom streamer. For writing, it will just do the normal thing. For reading, it checks the persistent class checksum. If there's a match with one of our registered converters, then rather than trying to read the object directly, we instead read it into a temporary instance of the persistent class, then call the converter to change it to a transient object.

Note that as long as the transient class has a ShowMembers method, then will not prevent the class from being split on output.
