The built-in explicit symplectic integrator has been replaced by a
general framework supporting run-time selectable integrators.  Currently
the explicit symplectic, implicit Crank-Nicolson and implicit Newmark
methods are provided, all of which are 2nd-order in time:

    Can only be used for explicit integration of the motion of the body,
    i.e. may only be called once per time-step, no outer-correctors may be
    applied.  For implicit integration with outer-correctors choose either
    CrankNicolson or Newmark schemes.

Resolves some stability issues with the outlet of multiphase problems.

read in the construction from dictionary.

It is important that the initial value is obtained from the table
provided to avoid the user having to evaluate a consistent one or risk
the code crashing from a very sudden change in the value.

For explicit motion (and the first iteration of iterative motion
correction) the 2nd-order symplectic motion integrator is used.

For iterative correction a form of lagged Crank-Nicolson is used in
which the current time-step values correspond to the current iteration.
This converges to a 2nd-order implicit solution.

    Solidification phase change model where all film mass is converted when the
    local temperature > activation temperature.  The latent heat is
    assumed to be removed by heat-transfer to the wall.

Now combinations of incompressible, compressible phases with or without
mass-transfer are supported efficiently.
