	Factory function that accepts any container type that can be passed through a range-for loop. This will insert the contents of _topics into a blank TopicList and then return it.
Static Public Member Functions inherited from QueryOptions
static SqlStatement	StandardMessageQueryClose ()
	Get a standard ending to a SQL statement that will instruct the queries to be ordered by the time the messages were received by the logger. It will also end the statement with a semicolon.
static SqlStatement	StandardMessageQueryPreamble ()
	Get a standard SQL statement preamble, from the SELECT keyword up to (but not including) the WHERE keyword. This preamble will make sure that the statement is formatted in a way that MsgIter will have the information it needs.
