Re: [boost] Geometry Template Library from Intel

After this morning's discussion I implemented what I've had in mind to
make the implementation of my library standard generic programming.  It
is just a demonstration of the GP interfaces I have in mind, and is
pretty simple. I define a point, interval, point_3d and rectangle
concepts and use them with each other.  For example the point_3d is also
a model for point_2d, and I use it that way, and the rectangle interface
is implemented in terms of the interval.  The coordinate type is
templated everywhere and I use that fact to demonstrate the
compatibility that enables between geometry objects with different
coordinate data types.

Near the end I show how a made up layout object data type, that has the
four coordinates of a rectangle as part of its member data, can be made
to model the rectangle concept by providing a specialization of
rectangle_traits for it and then I use it with another rectangle type
with different coordinate type.

Please feel free to critique the code.  I want to make sure I've got
everything right before I rewrite the library.

Thanks,
Luke
