New rule request

Since XCode has a class prefix setting option, I want a rule to check if public or internal class, enum, struct, and protocol have the prefix. However, it should be configurable to not require for inner class, inner enum, and inner struct to have the prefix. For example, if the prefix is CTA, the name of the first-level class must start with CTA, like CTADataModel.
