Stock Lab - 1.5hrs

You are going to create a simple Sinatra application that looks up Stock Exchange prices and returns the price to the user.

1. Create a one page Sinatra app (just one route to "/").
2. Use HTML and CSS to customise the layout.
3. Add a form with a field for the stock symbol, and a button to submit.
4. After the form is submitted, display to the user the stock symbol and the current price (retrieved from the internet using a Ruby gem -- you'll need to find one).

Some example stock symbols are:

Symbol	Company	Example Price
AAPL	Apple	116.47
GOOG	Google	537.5
AMZN	Amazon	332.63
MSFT	Microsoft	47.98
CAKE	Cheesecake Factory Inc	47.27
FIZZ	National Beverage Corp.	25.55
TSLA	Tesla Motors	242.78
GPRO	GoPro Inc.	70.72

Yahoo Finance gem

  # terminal
  gem install yahoofinance

  # ruby
  require 'yahoofinance'

  def get_standard_quotes(symbol)
    YahooFinance::get_standard_quotes(symbol)[symbol] rescue nil
  end

  stock = get_standard_quotes("aapl")
