#The code beolow will actually delete the Application pool and Web site that has been created above.
#NOTE:  You must delete the site and application pools that are retrieved from the Servermanager object
#       instead of using get-item otherwise you will get the following error "The configuration object is read only, because it has
#       been committed by a call to ServerManager.CommitChanges(). If write access is required, use ServerManager
#       to get a new reference."
