Library for describing & applying DOM changes with a primary emphasys of moving DOM UI work off the UI thread. Library provides Virtual DOM abstraction that application could use to in the web worker to describe the UI state. Versions of Virtual DOM can be diffed to produce a changelist encoded in efficient format like UintArray8 that is transferable to a UI thread where changlist can be then applied to an actual DOM tree. Library is designed to support use case without Virtual DOM abstraction (like Ember) by allowing direct authoring of DOM changelists that again can be encoded into UintArray8 in the web worker and then applied back on the main thread. At the moment library reached milestone where it can be put out there for feedback. Test coverage is shameful, so expect bugs. In fact main reasons to publish it this early is to get help with that.
