First version:
- Dynamically checking the correctness of an expression in the IDE (Blender).
- The task is divided into 2 parts: checking the correctness through python in the Blender interface and when performing calculations when the application is running in haxe.
The following decisions are taken as a basis:
python - http://repl.it/3xv/1
haxe - https://github.com/maitag/formula (added all the necessary classes to the node code)
