Setting a Custom Title and/or Description Using Doc Comments

If a struct, variant or field has any doc comments (or doc attributes), then these will be used as the generated schema's description. If the first line is an ATX-style markdown heading (i.e. it begins with a # character), then it will be used as the schema's title, and the remaining lines will be the description.
