Alex Lin 4dad11bf45 Ignore privacy
Moved field offset calculations for inherited classes to when the inherited
classes are processed.  This removes the need to have to remember if fields
were inherited or not, the offset already reflects the correct offset.

/**
This class is a recursive AST visitor that is called when a CXXRecordDecl node
is found. Inside of a CXXRecord we are only interested in 4 types of nodes, the
CXXRecord itself, template specializations, friends, and fields. If a field is
found a FieldVisitor is instantiated and parsing of the field continues in the
field visitor.
A class visitor is usually instantiated by the top level visitor, TranslationUnitVisitor,
or the typedef visitor, TypedefVisitor.
