Adam Duskett b2266009be package/odb: new package 
ODB is an open-source, cross-platform, and cross-database
object-relational mapping (ORM) system for C++. It allows you to
persist C++ objects to a relational database without having to deal
with tables, columns, or SQL and without manually writing any mapping
code.

ODB supports MySQL, SQLite, PostgreSQL, Oracle, and Microsoft SQL
Server relational databases as well as C++98/03 and C++11 language
standards.  It also comes with optional profiles for Boost and Qt
which allow you to seamlessly use value types, containers, and smart
pointers from these libraries in your persistent C++ classes.

This package is used for auto-generating ODB specific header files
into useable code that can be linked against a seperate libodb and a
specific libodb database library.  As such, it is only needed as a
host program and is not user selectable.
