 This minor release introduces a new operator, `startWith`, which is meant to replace the `initialValue` operator.

Subject: [PATCH 2/4] Use a reasonable fallback when adding visualization views
 to the runtime container view.

Summary:
We were assuming that target views would be part of the view hierarchy by the time runtime.add was invoked, but this isn't always the case. When there is no parent we'll fall back to a best-guess of the frame being the container view's bounds.

Closes https://github.com/material-motion/material-motion-swift/issues/101
