Allow adding additional sub/superscripts to symbols.

)abbrev domain SYMBOL Symbol
++ Author: Stephen Watt
++ Date Created: 1986
++ Date Last Updated: 7 Mar 1991, 29 Apr. 1994 (FDLL)
++ Description:
++   Basic and scripted symbols.
++ Keywords: symbol.
Symbol() : Exports == Implementation where
  L ==> List OutputForm
  Scripts ==> Record(sub : L, sup : L, presup : L, presub : L, args : L)

  Exports ==> Join(OrderedSet, ConvertibleTo InputForm, OpenMath,
        ConvertibleTo Symbol,
         ConvertibleTo Pattern Integer, ConvertibleTo Pattern Float,
          PatternMatchable Integer, PatternMatchable Float) with
     new : () -> %
       ++ new() returns a new symbol whose name starts with %.
     new : % -> %
       ++ new(s) returns a new symbol whose name starts with %s.
     resetNew : () -> Void
       ++ resetNew() resets the internals counters that new() and
       ++ new(s) use to return distinct symbols every time.
     coerce : String -> %
       ++ coerce(s) converts the string s to a symbol.
     name : % -> %
       ++ name(s) returns s without its scripts.
     scripted? : % -> Boolean
       ++ scripted?(s) is true if s has been given any scripts.
     scripts : % -> Scripts
       ++ scripts(s) returns all the scripts of s.
     script : (%, List L) -> %
       ++ script(s, [a, b, c, d, e]) returns s with subscripts a,
       ++ superscripts b, pre-superscripts c, pre-subscripts d,
       ++ and argument-scripts e.  Omitted components are taken to be empty.
       ++ For example, \spad{script(s, [a, b, c])} is equivalent to
       ++ \spad{script(s, [a, b, c, [], []])}.
     script : (%, Scripts) -> %
       ++ script(s, [a, b, c, d, e]) returns s with subscripts a,
       ++ superscripts b, pre-superscripts c, pre-subscripts d,
       ++ and argument-scripts e.
     subscript : (%, L) -> %
       ++ subscript(s, [a1, ..., an]) returns s
       ++ subscripted by \spad{[a1, ..., an]}.
     superscript : (%, L) -> %
       ++ superscript(s, [a1, ..., an]) returns s
       ++ superscripted by \spad{[a1, ..., an]}.
     argscript : (%, L) -> %
       ++ argscript(s, [a1, ..., an]) returns s
       ++ arg-scripted by \spad{[a1, ..., an]}.
     elt : (%, L) -> %
       ++ elt(s, [a1, ..., an]) or s([a1, ..., an]) returns s subscripted by \spad{[a1, ..., an]}.
     string : % -> String
       ++ string(s) converts the symbol s to a string.
       ++ Error: if the symbol is subscripted.
     sample : constant -> %
       ++ sample() returns a sample of %
