+Module: Hanging Protocol
+
+## Overview
+`hangingProtocolModule` provides the protocols for hanging the displaySets in the viewer.
+This module can be as simple as loading a list of pre-defined protocols, or it can be more complex
+and `fetch` the protocols from a server.
+
+```js
+const deafultProtocol = {
+  id: 'defaultProtocol',
+  locked: true,
+  hasUpdatedPriorsInformation: false,
+  name: 'Default',
+  createdDate: '2021-02-23T19:22:08.894Z',
+  modifiedDate: '2021-02-23T19:22:08.894Z',
+  availableTo: {},
+  editableBy: {},
+  protocolMatchingRules: [],
+  stages: [
+    {

+      viewportStructure: {
+        type: 'grid',
+        properties: {
+          rows: 1,
+          columns: 1,
+        },
+      },
+      viewports: [
