+// a Regular attribute of type T is one for which 
+// * the SC method takes a single argument of type ArgType<T> (defined below)
+// * Scb either passes that argument through, or dumps it in a buffer to flush later. 
+// * PVD is notified when the variable changes
+//
+// For each such, we can define static methods to read and write the core and buffered variables, 
+// and capture the buffering logic in the BufferedAccess class.
+//
+// The dummy arg is necessary here because ISO permits partial specialization of member templates
+// but not full specialization.
+//
+// putting just accessors and mutators here allows us to change the behavior just by varying the
+// BufferAccess template (e.g. to compile without buffering), and also to size-reduce that template 
+// by passing function pointers if necessary
