Setting CakePHP's webroot as document root.
    A CakePHP application has 3 important directories. "/cake", "/app" and "/vendor". To avoid having problems in deploying, do not rename the "/app" folder to anything if you want it to be your web host's root directory. Otherwise it will always display the /app's new name to the url address.

   If you rename "/app" folder to something like "/newApp", instead of having a url of "", it will display "".
