= PyRunner

This is a tool to run python code from Java.
The tool requires FULL python to be installed, including pip and venv.

Some python installations require manual post-installation of these. To do this you need something like
{{{
sudo apt-get update
sudo apt install python3-pip
sudo apt install python3.<VERSION>-venv
}}}

where <VERSION> is 8,9 etc depending on your python version.

The procedure is roughly:
* create a PythonVenv  E, possibly already with the targz code you want to run
 * Pass your targz directly into the PythonVenv constructor
 * or if you dont have a targz, copy the code into E.
* E.call the code you want to run
* call E.remove to remove the venv
