0.18 release

[FreezyLemon]

Is there a roadmap on what's planned to be included in the next release? I see the 0.17 milestone still exists but nothing similar for 0.18.

Was just thinking about adding that milestone, figure we've got a decent batch of breaking changes, so it would be nice to have this much break over just one release instead of over 0.18 and 0.19 - no guarantees for 0.19, but it would be nice.

The few things that may not break much code

• error handling from fallible construction of distributions and special function evaluations
  • expecting most usage is robust against this because unwrap was likely with how general the error type previously was.
• some generics with traits will be overridden to associated types
  • most Rust programmers rely on type inference,

to increasing likelihood of breaking code with changes

• multivariate distributions, guaranteed breaking
• some traits are changing API, i.e. a fix to #295 would break most cases.
