 * This function launches a new web browser window to a specified width, height and features.
 * Features string is a comma separated window's feature needed for this new window. For Instance
 * If a new window needs a toolbar the feature string must be "toolbar" like needs scroll bar and
 * and toolbar then it must be "toolbar,scrollbar". Note that the order of the feature is not required.
 * Also it's case insensitive. Therefore, "scrollbar,toolbar" is identical to "Toolbar,ScrollBar".
 *
 * NOTE: By default window will be shown at center of screen, if you'd like to display it at a specific coordinates
 *       pass the left and top properties as a feature string. 
 *       For instance, to display a window at 100px on X and 100px on Y set feature string as "left=100,top=100"
 *
 * If the features string is ommitted then all the features are turned off. To turn all the features on
 * use the word "all" for features instead of specifying each feature.
 *
 * @address URL to open in new window
 * @width width of new window in pixel. Defaults to 400 pixels.
 * @height height of new window in pixel. Default to 350 pixels.
 * @features feature string to have window features enable. Such as toolbars,menubars etc.
 * @name string if new window to be named window.
