/**
 * Superclass for all styles in AIDA Plotting package.
 * All styles can be reset to their original values at construction 
 * time. In the case of styles which 'contain' other styles (like IStyle 
 * or IAxisStyle), reset() calls reset() on the aggregated styles too.
 * All styles are hierarchical, so the plotter's current style is overridden by the
 * region's current style, which is overridden by any 'associated' style 
 * which is overwritten by any style passed in explicitly at plotting time.
 * Parameters and options which have been explicitly set to 
 * non-default (or default!) values are 'sticky'. For example, if a style
 * has the default 'red' and this has been set explicitly to 'blue' at the 
 * Plotter level, then it will override the default 'red' at the Region level.
 * IF the user explicitly sets the region to 'green' (or 'red'!) then it will
 * not be overridden by the 'parent' style.
