Function toposort

toposort(
    options: {
        allow?: Record<string, Named>;
        env?: Record<string, Named>;
        list?: Expr | Expr[];
    },
): ToposortResult
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.
Parameters
- options: {
      allow?: Record<string, Named>;
      env?: Record<string, Named>;
      list?: Expr | Expr[];
  }
  - 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?: Expr | Expr[]
    a single expression or a list of expressions to sort.
Returns ToposortResult
Example
```
const expr = ski.parse(src);
   toposort([expr], ski.getTerms()); // returns all terms appearing in Expr in correct order
```
