* 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
* add segLen help to lang std
* adding helpers functions to sketchConstraints
* update tokeniser tests because they were annoying me not being 100%
* compare async lexer with sync lexer instead
* add helper functions
* remove unneeded nesting
* update add ast modifier function for angledLine
* initial equal ast modification
It adds a tag to the primary line, and converts any secondary lines to angledLine, but doesn't reference the taged/primary line yet
* Update fn call with refernce to previous line using segLen
* add test for giveSketchFnCallTag
* fix excutor bug, executing call expression in array expression
* fix small issue in executor
* add CallExpressions to BinaryExpressions
* add unary Expressions
* tweaks to unaryExpression logic
* add recasting for unaryExpressions and CallExpressions in BinaryExpressions
* ensure pipe substitution info is passed down to unary expressions and others
* allow binary expressions in function argumentns
* inital setup, new way of organising sketch fn transforms
Starting with equal length

* improve modifyAst consision
* further modify ast tidy
* equalLength transfroms far angledLineOfXLength
* add transforms for line-yRelative
* add equal constraint for angledLineOfYLength
* quick test fix
* add equal length constrain transforms for lineTo
* add equal length constraints for angledLineToX
* add equalLength constraints for angledLineToY
* test tidy
* setup new vertical-horizontal constraints
* Add equal Length constraints for vertical/horizontal lines
