This class can be used to display a list of smiley icons all at once in a Web page.
It retrieves the list of icon images to display that are stored in a given server side directory.
The class can either generate HTML with tags to display all images in a single paragraph one after another, or a single image with smiley icons and HTML tags that define all the areas of the image that correspond to each icon.
In both cases, the class generates Javascript code to associate to events when each icon is clicked.
