Base class for unsteady solvers.
Initialises the arterial subdomains in m_vessels and sets up all domain-linking conditions (bifurcations, junctions, merging flows). Detects the network structure and assigns boundary conditons. Also provides the underlying timestepping framework for pulse wave solvers including the general timestepping routines.

Riemann Problem for Bifurcation.
Solves the Riemann problem at a bifurcation by assuming subsonic flow at both sides of the boundary and by applying conservation of mass and continuity of the total pressure The other 3 missing equations come from the characteristic variables.

Solves the Riemann problem at an interdomain junction by assuming subsonic flow at both sides of the boundary and by applying conservation of mass and continuity of the total pressure The other 2 missing equations come from the characteristic variables. For further information see "Pulse WavePropagation in the human vascular system" Section 3.4.

Sets up initial conditions.
Initialisation routine for multiple subdomain case. Sets the initial conditions for all arterial subdomains read from the inputfile. Sets the material properties and the A_0 area for all subdomains and fills the domain-linking boundary conditions with the initial values of their domain.

Solves an unsteady problem.
NEEDS Updating:
DoSolve routine for PulseWavePropagation with multiple subdomains taken from UnsteadySystem and modified for multidomain case. Initialises the time integration scheme (as specified in the session file), and perform the time integration. Within the timestepping loop the following is done: 1. Link all arterial segments according to the network structure, solve the Riemann problem between different arterial segments and assign the values to the boundary conditions (LinkSubdomains) 2. Every arterial segment is solved independentl for this timestep. This is done by handing the solution vector and the right hand side m_ode, which is the PulseWavePropagation class in this example over to the time integration scheme

Initialisation routine for multidomain solver. Sets up the expansions for every arterial segment (m_vessels) and for one complete field m_outfield which is needed to write the postprocessing output. Also determines which upwind strategy is used (currently only upwinding scheme available) and reads blodd flow specific parameters from the inputfile
Gets the Material Properties of each arterial segment specified in the inputfile from section MaterialProperties
Also gets the Area at static equilibrium A_0 specified in the inputfile.
Having found these points also extract the values at the trace points and the normal direction consistent with the left adjacent definition of Fwd and Bwd
