1. What did you get done this week:
I added gradient function to 3D raster library and than added r3.gradient
[3] module to addons. I tested it with and without OpenMP and it seems that
OpenMP doesn't really speed up the module, it usually slows it down. So I
will probably remove the OpenMP support completely. I also tried different
settings of cache but again, I found no significant improvement with other
than default settings. Then, I added more tests for r3.flow (and fixed a
bug) and r3.gradient. In the gradient function, I also added better
handling for NULL values.

2. What do you plan on doing next week?
I will move both modules in trunk next week. I will update manual pages.

3. Are you blocked on anything?
