Creates and returns a new named OraSession Object.
orasession = orasession.CreateNamedSession(session_name)
A string specifying the name of the session.
Using this method, you can create named sessions that can be referenced
later in the same application as long as the session object referred to is in scope.
Once a session has been created, the application can
reference it by way of the ConnectSession method or the OraSessions collection of
their respective OraClient object. The OraSessions collection only contains
sessions created within the current application. This means that it is not possible
to share sessions across applications, only within applications.
This method is provided for simplicity and is equivalent to the CreateSession
method of the OraClient object.
