Adds a AnchorLink.level property

[funkyfuture]

this allows themes to restrict the toc to a certain depth.

here's a proof-of-concept: squidfunk/mkdocs-material#450

Hmm, so this adds a level attribute to the AnchorLink class to track the "level" of each item in a template. Is that really necessary? Why can't you track that with a template variable? In other words, convince me this is the right approach to the problem.

Regardless, this would need to have some tests. Also, it should be against the 1.0.dev branch. Finally, as this would be a 1.0 feature, the template specific setting (in the associated Material PR) may want to take advantage of the new template settings implemented in #1201,

in general i tend to keep the logic in templates at a minimum and rather pass rich context objects. imo this is easier to read in the templates. also, all theme developers and users can easily access this information w/o implementing a logic for it. it's obviously simply implemented and maintainable on the Python side.

thanks for the other hints.

Add some tests and I'll give this another look.

a test is added. the fails are caused by missing interpreters.
