ISourcePointImplicit Interface

A point where a source contribution can be added, containing an implicit term in the form of a derivative with respect to the state variable.

Current usage is adding a source that depends on the water level, and including a water level derivative to take the change of water level into account, i.e. Q_s = Q_s^n + dQdh * (H^{n+1} - H^n)

The actual source added can be calculated using the Evaluate method after the time step has finished (at the PostTimeStepEvent).
