\class Field Field.h "vcf/FoundationKit/Field.h"
The Field class allows RTTI introspection to support member variables of
a class. There are some limits on how it works though, due to some
features of teh C++ langauge. At the very least you cannot use it
with member variables whose type is itself a class that has operator&
overloaded.
