Function toposort

toposort<T extends Expr = Expr>(
    options: {
        allow?: Record<string, Named>;
        env?: Record<string, Named>;
        list?: T | T[];
    },
): ToposortResult<T>
Topologically sort a list of terms, extending it with any missing dependency terms, if necessary. The output list is guaranteed to contain at least the input terms.
Type Parameters
- T extends Expr = Expr
Parameters
- options: { allow?: Record<string, Named>; env?: Record<string, Named>; list?: T | T[] }
  - Optionalallow?: Record<string, Named>
    a set of terms that are allowed in the returned list (aside from the input list).
  - Optionalenv?: Record<string, Named>
    a set of terms assumed to be known (and thus not required in the output list).
  - Optionallist?: T | T[]
    a single expression or a list of expressions to sort.
Returns ToposortResult<T>
Example
```
const expr = ski.parse(src);
   toposort([expr], ski.getTerms()); // returns all terms appearing in Expr in correct order
```
