/**
* This file defines the interface for the grist api exposed to SafeBrowser plugins. Grist supports
* various ways to require it to cover various scenarios. If writing the main safeBrowser module
* (the one referenced by the components.safeBrowser key of the manifest) use
* `self.importScript('grist');`, if writing a view include the script in the html `<script src="grist"></script>`
*
*
* Example usage (let's assume that Grist let's plugin contributes to a Foo API defined as follow ):
*
* interface Foo {
* foo(name: string): Promise<string>;
* }
*
* > main.ts:
* class MyFoo {
* public foo(name: string): Promise<string> {
* return new Promise<string>( async resolve => {
* grist.rpc.onMessage( e => {
* resolve(e.data + name);
* });
* grist.ready();
* await grist.api.render('view1.html', 'fullscreen');
* });
* }
* }
* grist.rpc.registerImpl<Foo>('grist', new MyFoo()); // can add 3rd arg with type information
*
* > view1.html includes:
* grist.api.render('static/view2.html', 'fullscreen').then( view => {
* grist.rpc.onMessage(e => grist.rpc.postMessageForward("main.ts", e.data));
* });
*
* > view2.html includes:
* grist.rpc.postMessage('view1.html', 'foo ');
