1.3 History

   The GRASP manual states as central to its philosophy ``...the use of surfaces both for displaying properties and as objects in their own right'' [1]. OESpicoli is a logical descendant of this statement. For surfaces to exist as ``objects in their own right'' they require a support system: creation, manipulation, and storage. OESpicoli provides all the necessary functionality to perform these tasks, along with the ability to compare surfaces. Accordingly, OESpicoli provides all the functions necessary to analyze surfaces.
