ng start with exit code 1

Hello,

after cloning the repo to my desktop I run ng start. It fails with exit code 1:

`86% hashingcrypto.js:97
this._handle.update(data, encoding);

It's because @angular/material has changed to need a peer dependency of @angular/cdk
So
npm install --save @angular/cdk
Also I had to add
import 'rxjs/add/operator/catch';
To google-books.service.ts
And change the material theme to:
@import "~@angular/material/prebuilt-themes/indigo-pink.css";
in styles.css

I'll submit PR with the changes but all that being said you may just want to lock down the dependencies used currently on master for easy moving to follow the steps on the other branchs.
So change package.json
and remove the ^ from @angular/material and rxjs to use those specific version:
"rxjs": "5.1.0",
"@angular/material": "2.0.0-beta.3",
