/**
* This is the main class for creating a UserTransactionService instance.
* This class is the client's main entry point into the transaction engine.
*
* The creation of a user transaction happens via a UserTransactionServiceFactory
* which is looked up by this object behind the scenes.
* Instances can be serialized to disk and re-read at a later time.
* Note: deserialization will only work in the SAME configuration as the
* one that did the streaming out. In particular, if no identical Atomikos
* transaction service is present in the target VM then the process
* of deserialization will be erroneous.
