Change name of repo to 'critta-espresso'

Hi @adamcc 

Can you please change the name of this repo so I can upload it to the Python global repository? There is another package with the name 'espresso' so we need a new one.

You can do this by going to "Settings" at the top of the page (its found beside "Insights"); there should be a text box where you can change the repo's name.

Let me know if you have any problems!
