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. refs #218

/**
|
|
|
|
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.
