Record termtosvg on how to add functions to your prompt

https://github.com/nbedos/termtosvg is awesome because we can embed svgs into the readme without linking out to asciinemas website.

• geometry is easy to extend
• lets say we want to show the current day in the left hand prompt, like date -u +"%a"
• first, make a function to do what we want: day() { date -u +"%a" }
• now add to the left prompt: GEOMETRY_PROMPT += (day)
• hmm, we want that on the left side: GEOMETRY_PROMPT=(day $GEOMETRY_PROMPT)
• and lets remove the right hand side one GEOMETRY_PROMPT[3]=
• Cool!
• if you want to see how functions are made, just check out functions geometry_path
• this is also a good way of seeing how to customize the shipped functions
• thanks for checking it all out!
