Contact Manager Tut: Building the Application Shell: Minor issues

> First, take a look at the require **elements** at the top of the view.

> Below the require **elements**, you can see a pretty standard structure.

There is only one require element, so shouldn't be plural.

> The router-view is provided by Aurelia and is a placeholder that **indicated** where the router should render the current route.

Should be "indicates".

There are a few code boxes that are set to 'JavaScript' and cannot be changed to TypeScript. Easy to workaround, but maybe confusing for beginners.

Open the Contact Manager tutorial section titled “Building the Application Shell” and search for the quoted wording about the require elements and router-view. Correct “elements” to “element” and “indicated” to “indicates,” then inspect the JavaScript code boxes and make TypeScript selectable where appropriate. Done means the prose is grammatically correct and beginners can choose the intended code language.
