Color integration

[gcuendet]

Hi, Super nice job you have done with this kinfu_remake! Thanks a lot. Ultimately, I would like to export the reconstructed surface as a colored mesh. I know that marching cube needs to be ported from PCL version (which I was using so far), as mentioned in issues #12, but first I wanted to try to integrate the colors from the RGB camera (in a similar way as what is done in PCL) and get a colored point cloud.

I tried to define a color volume, and integrate the colors in it but it seems I have a few problems with GPU memory management... Specifically, I get a
KinFu2 error: unspecified launch failure
when I try to access 3D coordinates of points in the cloud (obtained with
DeviceArray<Point> kfusion::cuda::TsdfVolume::fetchCloud(DeviceArray<Point>& cloud_buffer) const)

I know it's not extremely clear and I apologize for that. I guess I was wondering if maybe someone could point me in the right direction after looking at my implementation.

Finally found the memory problem! The color integration is not fully functional yet but this particular issue can be considered as solved.
