* 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.
* Rough engine prep changes (#135)
* rough changes for engine prep
* mouse movements working again
* connect to engine for startsketch, line, close and extrude
* some clean up
* Change perpendicular-distance constraint to something more intuitive to setting parallel distance
* delete
* add back
* force rename
* change name back
* try renaming again
* Refactor getNodePathFromSourceRange
getNodePathFromSourceRange wouldn't go as deep as it should have,
stopping at pipe expressions, when it should have followed as deep
into the ast as possible.
The fact that it stopped early then had other part of the code base that
expected this behaviour and it effected a lot, so a rather large refactor
* overhaul of getNodePathFromSourceRange
* quick fix for moreNodePathFromSourceRange
* minor bugs in moreNodePathFromSourceRange
* couple more tests
* add moveValueIntoNewVariable
* add UI for replacing valuse with variable
* update button text
