Detailed Description

template<unsigned NSTEPS>
class oomph::BDF< NSTEPS >

////////////////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////////////////

Templated class for BDF-type time-steppers with fixed or variable timestep. 1st time derivative recovered directly from the previous function values. Template parameter represents the number of previous timesteps stored, so that BDF<1> is the classical first order backward Euler scheme. Need to reset weights after every change in timestep.
