This application uses the AlphaVantage API. Setup a free account with them to
use this application. Create a file called apikey.json and create a single json
key value pair with "api_key" being the key and the value being your api key as
shown below. DO NOT TRACK YOUR apikey.json FILE. It's generally considered
good practice to always hide your API key.
{ "api_key" : "<YOUR API KEY GOES HERE>" }
