--        Name:  p.invocation
--      Purpose:  Construct a MediaWiki template invocation.
--  Description:  This function makes a template invocation from the
--                name and the arguments given. Note that it isn't
--                perfect: we have no way of knowing what whitespace was
--                in the original invocation, the order of the parameters
--                may be changed, and any parameters with duplicate keys
--                will be removed.
--  Parameters:  name - the template name, formatted as it will appear
--                    in the invocation. (string)
--                args - a table of template arguments. (table)
--                format - formatting options. (string, optional)
--                    Set to "nowiki" to escape, curly braces, pipes and
--                    equals signs with their HTML entities. The default
--                    is unescaped.
--      Returns:  String
