Update tsconfig.json

Update tsconfig.json

Now that Angular 2 and its dependencies are installed, we need to enable TypeScript’s experimental support for decorators and include the es6-shim typings. In the future decorators and ES6 will be the default and these settings will not be needed. Add "experimentalDecorators": true, "emitDecoratorMetadata": true to the "compilerOptions" section, and add "./typings/index.d.ts" to the "files" section. Finally, we need to add a new entry in "files" for another file, "./src/model.ts", that we will create. Our tsconfig.json should now look like this:

{
  "compilerOptions": {
  "noImplicitAny": false,
  "noEmitOnError": true,
  "sourceMap": true,
  "target": "es5",
  "experimentalDecorators": true,
  "emitDecoratorMetadata": true,
  "outDir": "./Scripts/App"
  },
  "files": [
  "./src/app.ts",
  "./src/model.ts",
  "./src/main.ts",
  "./typings/index.d.ts"
  ]
}
