RtConnectivity drives the CONNECTIVITYLIB connectivity estimators (coherence, imaginary coherence, phase-locking value, weighted phase-lag index, amplitude envelope correlation, …) from a background QThread. Each arriving data block is forwarded to the worker, which updates the windowed connectivity estimate and emits a CONNECTIVITYLIB::Network result carrying the current edge weights and node positions ready for visualisation.

The actual estimator and its parameters — frequency band, window length, connectivity measure — are configured through a CONNECTIVITYLIB::ConnectivitySettings instance, so this header only adds the threading, lifecycle and signal plumbing on top of the existing batch implementation.
