Common iterator class\&. 

This class does nothing but define nested typedefs\&. Iterator classes can inherit from this class to save some work\&. The typedefs are then used in specializations and overloading\&.
.PP
In particular, there are no default implementations of requirements such as \fCoperator++\fP and the like\&. (How could there be?)
