v0.6.0

Added:

• When deriving JsonSchema, the schema's title and description are now set from #[doc] comments (#7)
• When deriving JsonSchema on structs using a #[serde(default)] attribute, the schema's properties will now include default, unless the default value is skipped by the field's skip_serializing_if function (#6)

Changed:

• When the option_nullable setting is enabled (e.g. for openapi 3), schemas for Option<T> will no longer inline T's schema when it should be referenceable.
