Docker support for managing dependencies

It would really help if you could setup docker support for this project.

The TrainAndTest python module requires python2 and a host of dependencies. If I could pull a docker container with all these dependencies, it would make life much easier - I could docker pull and run python main.py db ... or python main.py net ... with no additional effort
Similarly, you could build off of a ROS docker container for the DeepLCD C++ code. Having a docker container would help tremendously.

If you provide a Dockerfile, the typical usage for the user would be:

$ git clone https://github.com/rpng/calc
$ cd calc/TrainAndTest # Assuming there is a Dockerfile here
$ docker build calc/train:1.0 .
$ docker run -it --volume="/home/foo/bar/calc:/home/root/calc" calc/train:1.0 bin/bash
root@ubuntu:/# cd /home/root/calc/TrainAndTest
root@ubuntu:/# python main.py -h

Here is an example docker file for voxblox.

rpng / calc
