Docker update

[spficklin]

This PR updates the Docker file to support the RScripts and the 3D python viewer so that users who want to use the Docker image to avoid installing all of the dependencies can do so.

This PR makes the following changes:

• In the Makefile:
  • the lastest images now have ACE hardcoded to 3.2.0 rather than develop. This is because the develop branch can have, at any point in time, experimental code. I think the latest image should be the latest of development version of KINC and not the latest of of ACE.
  • I changed the NVIDIA_HEADLESS option to be consistent between the cpu and gpu tagged images.
  • I added a new KINC_R_REVISION argument.
• In the Dockerfile
  • I updated section to behave differently for newer version of KINC. For example in 3.4.2 we have a much simplified make procedure that if not used does not install the scripts in the bin folder.
  • I added installation of R, KINC.R
• In the Documentation
  • I adjust the text to reflect the new additions for the docker images. However, I'm not 100% sure when to tell the user to use the -cpu and -gpu tagged images. That should be included as the current image name isn't correct in the commands.
  • I changed the docker command from nvidia-docker to just docker with the --gpus all option. I wasn't able to run the image with nvidia-docker as that didn't exist on my machine.

Unfortunately, all of these changes makes the image rather large and take a long time to build.

@bentsherman would you mind looking this over? If you don't have time for a functional review if you can just check the changes and see if you are okay with them?

The only outstanding item on this is clarification about the -cpu and -gpu tags on the images which is missing in the documentation.

Also, once this PR is merged and after we do the 3.4.2 release we can rebuild the images for DockerHub. For the 3.4.2 release we just have this PR and the other #171 . Then we can release!

Oh, one other note.... If you try to build the images you'll see some warnings when building KINC about unused variables. That has been fixed in #171 so no need to try to clean that up. It will go away once all the PRs are merged.

Hi @bentsherman. I believe I have resolved all of the issues you raised on this PR. I did update the Dockerfile a bit more to make it easier to build just a cpu or gpu version. Also I added a new develop tag and set latest to point to the actual latest release rather than the develop branch. Other than that, the only other changes I made were to fix issues.

Can you review again? I'm hoping to do a release on Monday for Iris.
