how to run on sample browser tests on desktop

[amiya-pattnaik]

Hi,
Hope you will be doing well, we just downloaded your project the sample one is working.we are using mac osx.

1. Should we have all the driver installed on local machine and set the class path. Can you ship all required browser under this framework and point the code to pick the browser driver from that folder ?
2. we could not find the method where the driver path is initialized like : System.setProperty("webdriver.chrome.driver", "/Applications/Chrome/2.35/chromedriver");
3. how to run test on parallel mode with different browser parallel like FF, Chrome for the same feature file
4. what is the option of case "desktop": in the DriverUtil.java, in what situation it will be used ?

Your help is highly appreciated.
