 - `editor.get([key])`: retrieves the object with key `key`. When called with no key, returns the entire store.
 - `editor.MCMCProgress()`: displays a progress bar during MCMC inference (work in progress).
 - `print` prints an object the results section (works both in WebPPL and vanilla Javascript).
-- `resumeTrampoline`: resumes trampolining WebPPL code; used for external library functions that need to do asynchronous work.
 
 We also ship the editor as `editor.ReactComponent`.

+ * Use cases:
+ * - Preserving the input selection ranges before/after reconciliation.
+ *   Restoring selection even in the event of an unexpected error.
+ * - Deactivating events while rearranging the DOM, preventing blurs/focuses,
+ *   while guaranteeing that afterwards, the event system is reactivated.
+ * - Flushing a queue of collected DOM mutations to the main UI thread after a
+ *   reconciliation takes place in a worker thread.
+ * - Invoking any collected `componentDidUpdate` callbacks after rendering new
+ *   content.
+ * - (Future use case): Wrapping particular flushes of the `ReactWorker` queue
+ *   to preserve the `scrollTop` (an automatic scroll aware DOM).
+ * - (Future use case): Layout calculations before and after DOM updates.
  *
- * Each and every declaration produces a function with the same signature. This
- * allows the creation of custom validation functions. For example:

- * - Deactivating events while rearranging the DOM, preventing blurs/focuses,
- *   while guaranteeing that afterwards, the event system is reactivated.

- *   reconciliation takes place in a worker thread.
- * - Invoking any collected `componentDidUpdate` callbacks after rendering new
- *   content.
- * - (Future use case): Wrapping particular flushes of the `ReactWorker` queue
