-//
-// This file implements the SetTheory class that computes ordered sets of
-// Records from DAG expressions. Operators for standard set operations are
-// predefined, and it is possible to add special purpose set operators as well.
-//
-// The user may define named sets as Records of predefined classes. Set
-// expanders can be added to a SetTheory instance to teach it how to find the
-// elements of such a named set.
-//
-// These are the predefined operators. The argument lists can be individual
-// elements (defs), other sets (defs of expandable classes), lists, or DAG
-// expressions that are evaluated recursively.
-//
-// - (add S1, S2 ...) Union sets. This is also how sets are created from element
-// lists.
-//
-// - (sub S1, S2, ...) Set difference. Every element in S1 except for the
-// elements in S2, ...
-//
-// - (and S1, S2) Set intersection. Every element in S1 that is also in S2.
-//
-// - (shl S, N) Shift left. Remove the first N elements from S.
-//
-// - (trunc S, N) Truncate. The first N elements of S.
-//
-// - (rotl S, N) Rotate left. Same as (add (shl S, N), (trunc S, N)).
-//
-// - (rotr S, N) Rotate right.
-//
-// - (decimate S, N) Decimate S by picking every N'th element, starting with
-// the first one. For instance, (decimate S, 2) returns the even elements of
-// S.
-//
-// - (sequence "Format", From, To) Generate a sequence of defs with printf.
