Week 4 Report.

1. This week I've done:

Libopencad is extended with:
- 2 new geometry types: ATTDEF and ATTRIB.
- Color is now a geometry attribute, so, it can be got by calling CADGeometry->getColor() (returns RGBColor struct).
- Libopencad docs prototype can be seen there (a lot of things are missed).

OGR CAD Driver extended with:
- All libopencad's file I/O was rewritten using VSIF.
- Arc, Face3D geometries.
- Now geometry color is attribute (given as IntegerList in RGB format).

2. Plan on doing next week:

Previous week tasks: add Polyline3D, LWPolyline, Ellipse support to CAD Driver.
Add hatch geometry to libopencad. Implement dimensions library output representation. Start working on R13-R14 DWG support.

3. Blocking:
None.
