Add helper code and demonstrate debugging

- [Instructor] So with my project template done,…the next obvious thing is to write some code,…code that I can debug.…So I need some candidate code.…What better candidate than code that we'll actually use…throughout this project.…So you'll see that in order to use the Vision API,…I will need to store configuration keys.…So I'll create a file called config.ts over here.…And things I'll provision in the Azure portal,…we'll see this in the future modules,…a key for the Vision API, for instance.…

So I need a place to store that configuration.…So I'll say export config.…Or rather, export let config,…'cause we're creating a variable.…And for now, let's just create a test key.…This is a test key.…And this is actually a json object so it will be like this.…Now, once I've created it over here,…I should be able to come to index.ts.…And I should be able to say import…from…config.…

And here, I should be able to use IntelliSense…and it'll basically complete this for me, so that's great.…So that part is working.…And now, I can say console.log,…
