Viewer Buffer
The Viewer Buffer is a memory area where the Memento Viewer stores the messages to display.
The Viewer Buffer is cleared at start-up of the Memento Application. Then, it accumulates all the incoming Ring Buffer messages that satisfy the rules of the Verbosity Filter.
The Viewer Buffer has a capacity of 250,000 message slots. This can be modified with the command line argument "history", a higher value means a higher memory consumption.
The Viewer Buffer can be cleared at any time by the user using the "Clear" control button of Memento GUI.
