Tested the installation on a clean new account. All looked great, but for the following minor points, which I am fixing in this PR:
fix install of mamba and testing;
add defaults to some of the prompts (when prompted "Y/n" in the installing script, I kept pressing Enter, which raised an error);
I had a couple of time-outs because of the waiting to the Jupyter server to start. I think we can set this to longer wait times (I have put it here to 5 mins).
