Detailed Description

Helicity source that generates a reproducible sequence from seeds.

The QwFakeHelicity class uses a pregenerated random seed to generate the fake helicity signal that then can be used to perform helicity related calculations.

Used for testing and simulations when real helicity decoding is not available. Inherits the helicity interface and overrides event handling.
