Complete installation script for Ubuntu 20.04

Oh, I think that's a pending issue: Abseil has dropped support for C++11, so I think we need to do the same here.

You can reuse the .precommit.bazelrc file instead of making your own (--bazelrc=...).

[danijar]

Good to know about --bazelrc=.... The .precommit.bazelrc specifies --cxxopt=-std=c++11 though, wouldn't that be an issue? Without any .bazelrc I got an error that the build requires at least C++ 14.

We need to add a Dockerfile to this project.

We need to add a Dockerfile to this project.

Would love an official dockerfile but you can pretty easily adapt this installation script to work with docker:
