Not compatible to ndarray 0.12.0

[astrojhgu]

when using with ndarray 0.12 following error raises, and switching to 0.11 makes it work

    = note: expected type `ndarray::ArrayBase<ndarray::ViewRepr<&f64>, ndarray::dimension::dim::Dim<[usize; 1]>>`
               found type `ndarray::ArrayBase<ndarray::ViewRepr<&f64>, ndarray::Dim<[usize; 1]>>`

Hi there!

Thanks for reporting the issue. Could you give a minimal example that exhibits the behaviour? I'm not able to reproduce.

Hi, I place a test code at this respository.

I compile the code with rustc 1.32.0-nightly (8b096314a 2018-11-02).

If you set the ndarray version to 0.11.0, then it compiles, if you change it to 0.12.0, following error message appears: ` error[E0308]: mismatched types --> src/main.rs:21:9	21	Array1::::from_vec(vec![100.0,100.0]).view()	^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ expected struct ndarray::ArrayBase, found a different struct ndarray::ArrayBase

Actually, I find that simply change ndarray version from 0.11 to 0.12 can solve this problem.

However, I noticed the structure of this crate has been changed: Minimizer seems to be removed and Builer moved from root to vector.
