+/**
+ * Base Abstact Class for TimeAxis views that operate purely within the visual domain.
+ * 
+ * This class provides many of the common methods required for visual TimeAxis views. The aim is
+ * to provide an abstract layer during the developmnt of the visual based time axis'. Many of these
+ * methods have a better home further up the class heirarchy, and in fact some are replication of 
+ * methods found within RouteUI. This, however, has been required due to various problems with previous
+ * versions of g++, mainly 2.95, which are not correctly handling virtual methods, virtual base classes,
+ * and virtual methods when used with Multiple Inheritance. Perhaps these could be combined once the
+ * compilers all agree on hos do to do stuff...
