Creates a profile image with a set of user initials in it.
This allows you to create a PNG image using a user's initials on a circle, with the color set by a provided string (e.g. a User ID or their full name) to better differentiate between users. It is an improvement on the typical "mystery man" approach.
- Flexible implementation allows you to write to a cache or render inline
- Font color adjusts for readability on a particular background
