Subject: [ruby-core:66005] [ruby-trunk - Feature #10442] Helper methods to	Vector class

Issue #10442 has been updated by gogo tanaka.


@Egunov Dmitriy

I like this idea, and it looks fine for me.

It may too trivial things but I want more tests and to make it more gracefully.
(`1.5707963267948966` is little bit not clear)

Anyway, I respect for your work. thanks.

```
 assert_in_epsilon(Math::PI/2, Vector[1, 0].angle_with(Vector[0, 1]))
 assert_in_epsilon(Math::PI/4, Vector[1, 1].angle_with(Vector[0, 1]))
```

Vector class missed some very helpful methods like angle between another vector and vector projection.

Patch attached. Please advice if more unit tests are needed.
