/**
 * OldStyleTable: Layout tables using the old table style.
 *
 * Usage:
 * <pre>
 *  <<OldStyleTable border||=0 summary=""
 *  ||  __Name__               |v __Cost__   |v __Notes__
 *  | __First__   | __Last__
 *  |> Jeff       |< Dairiki   |^  Cheap     |< Not worth it
 *  |> Marco      |< Polo      | Cheaper     |< Not available
 *  >>
 * </pre>
 *
 * Note that multiple <code>|</code>'s lead to spanned columns,
 * and <code>v</code>'s can be used to span rows.  A <code>&gt;</code>
 * generates a right justified column, <code>&lt;</code> a left
 * justified column and <code>^</code> a centered column
 * (which is the default.)
