* Fix button text size
* guard against undefined window
* Formatting and test fix
* Intital async of executor
The execture now sends websocket message instead of calling functions
directly from the engine, When it does so it holds onto the id.
The engine is still returning geo/polys directly but I'm working make it
so that the UI doesn't need to know about that, so that we can switch
over the streaming ui.
Things left to do:
- it is still making both direct function calls and websockets, and the former should be removed.
- It does highlighting of segments and sourceRanges not through websockets and that needs to be fixed.
- Tests have not been adjusted for these changes.
- Selecting the head of a segment is not working correctly again yet.
