Group the content in Version class?

[tomschr]

I've read the book Clean Python: Elegant Coding in Python by Sunil Kapil. The author describes a lot of interesting things to improve the code. I would like to discuss one idea.

In chapter 3. Writing Better Functions and Classes, the author recommends:

Class Structure
I prefer a class structure in this order:

1. Class variables
2. __init__
3. Built-in Python special methods (__call__, __repr__, etc.)
4. Class methods
5. Static methods
6. Properties
7. Instance methods
8. Private methods

Probably there are other ways to group the content of classes, but it makes sense to me.

After looking at src/semver/version.py, the methods in the Version class looks a bit disorganized to me. So I'm tempted to group them according to Kapil's scheme. There are no feature changes, only lines that are moved around.

As we only have one open pull request (which belongs to me anyway) I think it would be small risk to take. I can't think of any downside right now.

Any concerns?
