This class is a time integrator for general Runge Kutta forms. It only includes
Pointintegrals with piecewise linear test functions. Such problems are disconnected at the vertices and can therefore be solved locally.
Construct a PointIntegralSolver
- scheme (_MultiStageScheme_)
- The multistage scheme the PointIntegralSolver is going to use to solve the PointIntegrals
Return the MultiStageScheme
