Issue #110 introduced type aliases to Mun - on a file-level. We want to extend this, such that - similar to Rust - Mun can support type aliases in a local scope:

type OtherTypeName = i32;
fn main() {
    type Typename = OtherTypeName; // Type alias in local scope
    let a: Ty

if we execute mvn test, then tests in BasicUITest fail.

executed standalone mvn test -Dtest=BasicUITest it works correctly.

since is MU is no longer in ember, I think we good to go to remove any MU related code, to simplify codebase
