     * Class: $.jqplot.ThemeEngine
     * Theme Engine provides a programatic way to change some of the  more
     * common jqplot styling options such as fonts, colors and grid options.
     * A theme engine instance is created with each plot.  The theme engine
     * manages a collection of themes which can be modified, added to, or 
     * applied to the plot.
     * 
     * The themeEngine class is not instantiated directly.
     * When a plot is initialized, the current plot options are scanned
     * an a default theme named "Default" is created.  This theme is
     * used as the basis for other themes added to the theme engine and
     * is always available.
     * 
     * A theme is a simple javascript object with styling parameters for
     * various entities of the plot.  A theme has the form:
     * 
     * 
     * > {
     * >     _name:f "Default",
     * >     target: {

     * "seriesStyles" is a style object that will be applied to all series in the plot.
     * It will forcibly override any styles applied on the individual series.  "axesStyles" is
     * a style object that will be applied to all axes in the plot.  It will also forcibly
     * override any styles on the individual axes.
