Fractal helper returns new instance every time

[siarheipashkevich]

Calling fractal() I'll get a new instance of the Fractal but not a single instance.

Is it correct behavior?

I guess so.

If I set recursionLimit using Fractal::limitRecursion(100); then it will be ignored calling helper method, is it?

If this is a problem, I'd appreciate a PR that fixes it 👍
