This is a (slightly janky) Python wrapper around memray's CLI interface.
Why is this better than a simple subprocess.call(['memray', 'run', 'myfile.py']...)? Well, it comes with a convenience function that lets you run a profile, generate a flamegraph, and (optionally) display the resulting flamegraph in your Jupyter cell, in a single Python function call. That's the main value-add right now.
