`string` is the string used to generate the initials. This should be a user's full name if available.
3839

3940
`color` is an optional parameter that sets the background color of the image. Pass in `nil` to have a color automatically generated for you.
4041

`isCircular` is a boolean parameter that will automatically clip the image to a circle if enabled.

44+
`fontName` is a NSString that specifies a custom font. See all String Identifiers for built in iOS fonts [here](http://iosfonts.com).
