Nasdaq Stock Price Checker

User Stories:

1. I can GET /api/stock-prices with form data containing a Nasdaq stock ticker and recieve back an object.
2. In the recieved object, I can see the stock (string, the ticker), price (number), and likes (number).
3. I can also pass along field like as true (boolean) to have my like added to the stock(s). Only 1 like per IP address should be accepted.
4. If I pass along 2 stocks, the returned object will be an array with both stock's info and in addition to likes, it will also contain rel_likes (the difference between the likes on both) on both.
5. A good way to receive the current price is the following external API (replace 'stock' with the stock ticker and 'API_KEY' with the API key):
   https://www.alphavantage.co/query?function=global_quote&symbol=stock&apikey=API_KEY
   (Get your free API key here)
6. All 5 tests are complete and passing.

Example usage:

• /api/stock-prices?stock=goog
• /api/stock-prices?stock=goog&like=true
• /api/stock-prices?stock=msft
• /api/stock-prices?stock=msft&like=true
• /api/stock-prices?stock=goog&stock=msft
• /api/stock-prices?stock=goog&stock=msft&like=true

Example return:

[{"stock":"GOOG","price":0,"likes":0}]
[{"stock":"GOOG","price":0,"likes":0,"rel_likes":0},{"stock":"MSFT","price":0,"likes":0,"rel_likes":0}]
