Hype MutationObserver

This is a Hype MutationObserver, a wrapper for MutationObserver (without polyfill for it). Will keep polyfills from now on separate, so projects that already use them don’t load them twice.

I get an error with the download:

Is fixed. Your welcome.

1.1 Added support for Updaterate

Use updaterate on the config object to set it up.
If you use the new updaterate feature to limit the amount of triggers on your mutation code, the extension also takes care to apply the first inital update and the last update. If you don’t want that you can disable them using the config keys disableInitialUpdate and disableFinalUpdate

Visual explanation of updaterate:

PS: As seen on the right hand side of the visualization, the check against the updaterate is not always on the heartbeat of the interval. That is rather what Hype AnimationFrame is for. So if a mutation event falls inbetween to heartbeats (interval) and more time has passed then an interval, it gets fired. That also always sets up a delayed timeout callback to fire any cached mutations in the next interval as a final update.
