* @version 1.0
* Based on base classes from org.apache.commons.fileupload
* Explenation of Strings:<br>
* public String folder:: This string contains the information of your local
* directory for testing your application locally.
* <br>
* public String tempFolder:: This is the location of your temp folder when
* testing the application locally.
* <br>
* public String serverFolder:: Uncomment this line when transfering the
files
* to the server. This is the complete string from the server root.
* <br>
