56	+	{ Database Journalling.
57	+
58	+	This class is intended to support a client side journal of all database
59	+	updates, inserts and deletes made by the client during a session. It also records
60	+	the transaction each update was made under.
61	+
62	+	The database schema is required to include a control table "IBX$JOURNALS" and
63	+	an SQL Sequence IBX$SESSIONS. These are created by the class when the
64	+	database is opened, if they are not already present. However, it is recommended
65	+	that they are created as an orginal part of the database schema in order to
66	+	unnecessarily avoid each user being given sufficient priviledge to create tables
67	+	and Sequences.
68	+
69	+	Syntax:
70	+
71	+	Transaction Start:
72	+	*S:<date/time>,<attachmentid>,<session id>,<transaction no.>,<string length>:<transaction Name>,<string length>:<TPB>,<default Completion>
73	+
74	+	Transaction Commit:
75	+	*C:<date/time>,<attachmentid>,<session id>,<transaction no.>
76	+
77	+	Transaction Commit retaining :
78	+	*c:<date/time>,<attachmentid>,<session id>,<transaction no.><old transaction no.>
79	+
80	+	Transaction Rollback:
81	+	*R:<date/time>,<attachmentid>,<session id>,<transaction no.>
82	+
83	+	Transaction Rollback retaining:
84	+	*r:<date/time>,<attachmentid>,<session id>,<transaction no.><old transaction no.>
85	+
86	+	Update/Insert/Delete
87	+	*Q:<date/time>,<attachmentid>,<session id>,<transaction no.>,<length of query text in bytes>:<query text>
