API structure (HLU function interface)

Functions that apply to all HLU classes are called base functions. This is because they are defined for all objects that are members of the Base class. There are specific functions that apply to only one type of class. There is one function, NhlDraw, that applies to two high-level classes that contain many subclasses. Finally, there are a few general functions which are not class-related. The functions are listed below by category.
