// Function:   NewPopupWindow() 
// Arguments:  url, window name, width, height, center window, window features
// Purpose:    This function will create a new window and set the appropiate parameters
// Notes:      * Window Name is used to set the target window.  Use this parameter to create seperate windows and to re-use existing windows.
//             * w & h accepts both length and percentages for both width and height. Example: '550','260' or '75%','45.68%'
//             * centered argument is a yes|no flag whether to center the new window or not.
//             * winFeatures argument is used to pass any extra window parameters. Example: 'menubar,toolbar,location,scrollbars,status,resizable'
//             * To fix the location of the new window don't center the window and add the 'top=' and 'left=' values to the winFeatures parameter.
//             * To use the default window width and height then pass blank or no value for w & h. Example: '',''
//             * To dynamically control the new window after it is created use the oPopupWindow object reference.  FYI: Declare oPopupWindow variable outside the function so it is in global scope.
