Macro tealr::new_type

macro_rules! new_type {
    ($type_name:ident,BuiltIn) => { ... };
    ($type_name:ident,External) => { ... };
    ($type_name:ident) => { ... };
    ($type_name:ident,Generic) => { ... };
}

An easy way to implement TypeName::get_type_parts if it only needs to return a single type without generics.

let name =  tealr::new_type!(Example, External);
assert_eq!(name,Cow::Borrowed(&[tealr::NamePart::Type(tealr::TealType{
    name: Cow::Borrowed("Example"),
    type_kind: tealr::KindOfType::External,
    generics:None
})]))
