/*
Prototype for the usage of this class is given for NoDynamics.
 
Use FixedDensity & ZeroMomentum for NoDynamics, BounceBack(rho), BounceBackAnti(rho)
Use BulkDensity & ZeroMomentum for BounceBack(), BounceBackAnti(), ZeroDistributionDynamics
Use FixedDensity & FixedVelocityMomentumGeneric for BounceBackVelocity(rho, u)
Use BulkDensity & FixedVelocityMomentumGeneric for BounceBackVelocity(u)
Use FixedDensity & OffBoundaryMomentum for OffDynamics (not yet ready)
 
For now, the BounceBack* classes may therefore be separated into the cases whether
rho is fixed or not. They can later be reunified/ given a logical structure, when it
is clear how the dynamics will be constructed in the future.
