The comments configuration is currently an object with 5 customisations expressed as Bool and 1 main isEnabled flag.

In my head, we could express this the same way with an enum/option set of values and a single commentFeatures array/set.. Something like the following:

Disable Comments:

commentFeatures: []

Everything:

commentFeatures:
- title
- description
- example
- externalDocumentation
- capitalized

Description (capitalized):

commentFeatures:
- description
- capitalized

In Swift, this would be something like the following:

public enum CommentFeature: String {
    case title, description, example, externalDocumentation, capitalized
}

public var commentFeatures: Set<CommentFeature> = [.title, .description, .example, .externalDocumentation, .capitalized]

Alternatively I'll just deswiftify the boolean properties on the existing object.
