Internal Source Code Naming Conventions
---------------------------------------
o API class X will almost always have associated internal (usually
private base) class named XI
o for class X there will be
o X.h - the class declaration (and simple inlines)
o XIL.h - complex inline functions (that will not
compile with until the compiler has seen
o for class X there will
o sometimes be X.h - the class declaration (and simple inlines)
o sometimes be XIL.h - complex inline functions (that will not

the declarations of other classes)
o X.cc - all other source code for the class
