Setup basic docker build and run scripts

[johncarl81]

Description

This PR sets up a development docker environment for the swarmathon team to develop in a common environment. Here we use docker to produce a container for our ros controllers to run, which interfaces to the srcp2 docker container via the srcp2net network and the hosted roscore.

build.sh builds this container by setting up the necessary system dependencies, sets up the ROS and srcp2 dependencies and builds the project.

runREPL.sh runs the container with a mapped directory so development may be done locally with the docker container drawing off of those files. This allows a python repl to aid in rapid development.

To test run the following:

./build.sh

then to run the REPL:

./runREPL.sh

Implements: https://github.com/BCLab-UNM/SC2/issues/182

So I was able to build but when I try to do ./runREPL.sh I get on 07b69270c4efe52710eae0697c18b5e3019fc187

Hmmm, I remember you tweaked the simulation to run it with your host networking. Is that still in place?
