+ 1.01 12 May 1999 Laurence Tratt
+
+ * Changed swi.error to be a class based exception rather than string based
+ * Added swi.ArgError which is generated for errors when the user passes invalid arguments to
+ functions etc
+ * Added "errnum" attribute to swi.error, so one can now check to see what the error number was
+
+ 1.02 03 March 2002 Dietmar Schwertberger
+ * Added string, integer, integers, tuple and tuples
