/**
 * A theme. - A theme is a collection of color choices and (possibly) images
 * that style a Portal. A theme is inherently tied to to the underlying design
 * of the portal page; for example, a theme that stores and sets a color for a
 * context bar is only useful if the design of the Portal that uses such a theme
 * has, in fact, a context bar.
 * <p>
 * A particular portal design/layout is made up of components such as context
 * bar, colored horizontal rules, tabbed panes...etc. which we refer to as a
 * <i>skin</i>. A skin can have a theme applied to it, which renders components
 * with desired colors, fonts, and background images. This Theme class is for
 * enhancing the default skin that ships with Portal Server.
 * <p>
 * If a developer desires to create their own Portal design or skin, then the
 * following files would be need to be implemented:
 * <ul>
 * <li> A PDL file describing the data model for the skin's thematic elements.</li>
 * <li> A class like this one that implements Themes, with getter/setters for
 * thematic elements</li>
 * <li> A CSS sheet with class names that correspond to the class names that the
 * <code>buildStyleBlock() </code>method uses (see below)</li>
 * <li>Appropriate XSL sheet that utilizes the CSS class names.</li>
 * </ul>
 * <p>
 * This class provides setters and getters for all of the elements in the
 * default Portal Server skin, plus a method that builds a block of CSS tags
 * that are inserted into the output stream and used to override default choices
 * for the default skin.
