Dirac documentation missing Continuous trait

[drtconway]

Hi Statrs,

Trivial bug. The current documentation (as of 0.18.0) https://docs.rs/statrs/latest/statrs/distribution/struct.Dirac.html has ContinuousCDF in the the trait implementation TOC but doesn't have Continuous even though it does appear to implement it.

Hey, unless I'm missing something, Dirac does not actually implement the Continuous trait. If it did, the documentation should also include this because it automatically generates those connections.

[drtconway]

Yes, I think that is correct - I was mislead by the example in the documentation which imports Continuous. I guess that's a minor bug.

In addition to dropping the import in doctest, might be valuable to add some context to the docs for these traits since implementing distributions with functions won't always work, so we may not implement both traits.
