Simple math expression

Complex math expression

Reference editing node with "this"

Reference any property of any node

Or script variable

- Since the implementation is using Godot's script interface, any valid script expression could be used
- Cons:
Script been re-created for each eval operation;
"this" keyword might be confusing
