GetEventTypes - Get event types (= unique descriptions).

  USAGE

    descriptions = GetEventTypes(selection)

    selection      optional patterns of event descriptions; see examples below

  EXAMPLES

    % Get all event descriptions
    descriptions = GetEventTypes();

    % Get events with description starting with any letter
    % but 'R' and ending with ' beginning'
    m = GetEventTypes({'[^R].* beginning'});

  NOTE

    Type 'help regexp' for details on pattern matching using regular expressions.
