- cleanup & refactoring of visualEditorView
 * moved out grid, cage, plane, axes etc , to a seperate "helpers" module : created reusable classes for all of these
 * removed old unused code, moved to the "old" file in the same folder for now
 * added seperate text color setting (for axis , dimention etc labels)
- more cleanup of html & css & js for code editor "dialog":
 * fixed a certain number of positining & functionnal issues, but still not 100% there yet (problems with not having actual full height container need to be resolved)
