Bernhard F.W. Gschaider a72b12ce8f This solves a compilation problem in Clang 3.5 where the class Time is 
not completely instantiated in objectRegistry (see error message
below)

By including objectRegistry.H before Time.H the class Tiem gets
completely defined before objectRegistry.

The original Time.H could be omitted (as it is already included in
objectRegistry.H )

c ======================================================================

cell 'i4' is connected to vertex 'i4'.
To get the points of cell 'i' is thus done in the following way:

i
i1tab(i)
i3tab(i1tab(i))
i3tab(i)
i8tab(i)
i1tab(i8tab(i))
i3tab(i1tab(i8tab(i)))
i3tab(i8tab(i))

Only three of the faces have boundary condition. They are stored in the following arrays

bcl - boundary condition left face
bcf - boundary condition front face
bcb - boundary condition bottom face

To get the other boundary conditions, you must get the neighbouring cells
and obtain the bc from them.

The bc values are:
1.0  - moving  - moving (piston top)
2.0  - solid   - solid (wall)
3.0  - axis    - center axis, line
4.0  - fluid   - fluid (i.e. no bc)
5.0  - periodf - front periodic bc
6.0  - periodd - back periodic bc
7.0  - inflow  - inflow
8.0  - outflow - outflow
9.0  - presin  - pressure inflow
10.0 - presout - pressure outflow

c ======================================================================

fv - flag for vertices

The values are:

0.0 - inactive vertex
1.0 - flfluid - interior (fluid) vertex
2.0 - flface  - vertex on a moving surface (piston/valve)
3.0 - flbowl  - vertex within the piston bowl
4.0 - flsqsh  - vertex in squish region and above piston
5.0 - fldome  - vertex within head, but not on the surface itself
6.0 - flhead  - vertex on the head surface

c ======================================================================

f - flag for cells

The values are:

0.0 - inactive (ghost) cell
1.0 - active cell

c ======================================================================

idface - vertex flag for moving surface

The values are:

-1 - Not on a moving surface
 0 - Piston top
 1..6 - Valve nr.

c ======================================================================

idreg - cell region number.

c ======================================================================

The first non-ghost cell will be '
