[Axiom-developer] Lisp function signatures

[daly]

The lisp code is being enhanced with function signatures.

In addition, the list of all signatures, with page numbers is included 
as a separate compilation at the end of the document. For instance,

115 set-restart-hook : Void -> 'restart

131 intloopReadConsole : (String Integer) -> Throw

137 intloopPrefix? : String -> Union(String,NIL)

139 intloopProcessString : (String,StepNo) -> StepNo

140 next : (Function,Delay) -> Delay

140 next1 : Delay -> ParsePair

141 incString : String -> Function

144 setCurrentLine : String -> List(String)

144 mkprompt : Void -> String

146 serverReadLine : Stream -> String

167 intloopProcess : (StepNo,Boolean,Delay) -> StepNo

177 incRenumber : Delay -> Delay

177 incZip : (Function,Delay,Delay) -> Delay

177 incZip1 : Delay -> ParsePair

178 incIgen : Integer -> Delay

180 incLude : (Int,List(String),Int,List(String),List(Int) -> Delay

204 incCommand? : String -> Boolean

207 Delay : (Function,List(Any)) -> Delay

441 StreamNull : Delay -> Union(T,NIL)
