Async download of stock or dividend quotes from yahoo finance.
Example of usage in coffeescript:
YahooQuotes = require 'yahoo_quotes'
yq = new YahooQuotes("ibm", "2012-12-01", "2012-12-31", "prices")
yq.on 'error', (err) -> throw err
yq.on 'data', (yahoo_rec_list) -> for q in yahoo_rec_list console.log("%s,%s", q.iso_date, q.close_price)
In the above example, yahoo_rec_list is an array of objects. Each object has the following fields: iso_date, open_price, high_price, low_price, close_price, volume, and adj_close.
When used to fetch dividends, each object will have two fields: iso_date and dividend.
The arguments to YahooQuotes are: ticker, iso_start_date, iso_end_date, result_type.
The result_type field defaults to 'prices', which stands for daily price quotes. Other valid values are: weekly_prices, monthly_prices, and dividends.
