* 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
* overhaul equalLength button
* add equal length support for angledLine
* line with one variable supports signed legLength
* fix indentation when recasting long arrayExpressions in a pipeExpression
* 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
* migrate old tests, and refactor callback tag
* tweaks and refactor horzVert component
* fix leg len with small negative leg length
* update execution of callExpressions
* tweak types to store multiple cursor ranges and hook up with artifact highlighting
* multi-cursor from 3d scene
Working but has to be capslock for the time being
* tweak pannel headers
* add issue to todo comment
* functional sketch working
With old sketch block still there
* get all version of lines working with add line and update line
* remove old ui state types
* some clean up
* rename some things
* add todo for multi cursor
* shorten useStore repitition
* small type improvement
* big overhaul to group sketch function and they ast modifying helpers together
* unneeded tweak
* ruthlessly rip out sketch logic
* clean up path keyword
* getting sketch on face working again with all the new sketch line types
* add a bunch of tests and re-arrage file structure
* Revert "wire up comments to ui (#11)"
This reverts commit bdf778530f.
* Revert "Add the ability to recast comments and some whitespace (#10)"
