Add simple instructions for dependencies, build, and install

[bignose-debian]

There is no top-level document (e.g. the Read Me) stating how to satisfy dependencies, build, and install this code base.

There are CMake files, a Distutils script, a Vagrantfile, a Makefile. Which of those should the recipient use to satisfy build dependencies? What commands to run for building, for installing?

A simple text in the Read Me document (or, if they are more complex, maybe a separate INSTALL document) that says something like:

Get build dependencies:

    $ python3 -m pip install foo bar baz

Build this code base:

    $ cmake lorem/
    $ python3 -m setup build

Install the library:

    $ make install

would be enough to satisfy the recipient's need to know how to do those things.
