The \footnotestyle command is always used in conjunction with the
\footnoteformat (\fnf) command, and will set the numbering style for the
footnotes. The format for the \footnotestyle command is:
\footnoteformat{
\footnotestyle{xx}
}
Where "xx" is one of four possible values:
1 which gives numbered footnotes 1, 2, 3, etc.
(1) which gives numbered footnotes included in parentheses (1), (2)
a which gives lettered footnotes a, b, c, etc.
(a) which gives lettered footnotes enclosed in parentheses (a), (b)
