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
Mostly working. This removes the use of offsetof from all I/O code. This was
the only reason we needed friends. In it's place we put the offset value that
clang has calculated for the field. Still need to work on virtually inherited
classes and confirm bitfields.
refs #218
Changed all header file once include variables to follow the same naming
convention and not start with any underscores. Also deleted old
incorrect copyright notices. Also removed $Id: tags from all files.
Fixes#14. Fixes#22.
