Installing Python packages using Pip

Convention: Use python process to invoke Pip

We don't use this convention (yet) but this is an upcoming change being considered.

This is a bigger concern on Windows than it is in Linux environments, but an emerging convention in the Python community is to invoke pip using:

python3 -m pip [options]

Invoking pip this way ensures correct location - python knows where these packages are stored because it put them there (defaults to Python's pathing info).

All normal command line options are available using this method.
