Cron Job

[heiden12]

Create a cron job to automatically pull down and save intraday stock data every night. This has two parts:

1. Create a shell script that runs the matalab function (with no display) and copies the data to our web server.
2. Schedule the cron job so the shell script gets run nightly

I think we should add "default" ticker values if none are supplied, this way the save data function can be run more easily with a cron job and shell script.
