ENH: overset: Initial release of overset capability.

Adds overset discretisation to selected physics:
- diffusion : overLaplacianDyMFoam
- incompressible steady : overSimpleFoam
- incompressible transient : overPimpleDyMFoam
- compressible transient: overRhoPimpleDyMFoam
- two-phase VOF: overInterDyMFoam

The overset method chosen is a parallel, fully implicit implementation
whereby the interpolation (from donor to acceptor) is inserted as an
adapted discretisation on the donor cells, such that the resulting matrix
can be solved using the standard linear solvers.

Above solvers come with a set of tutorials, showing how to create and set-up
simple simulations from scratch.

Description
Laplace equation solver for a scalar quantity.
\heading Solver details
The solver is applicable to, e.g. for thermal diffusion in a solid. The
equation is given by:
\f[
\ddt{T} = \div \left( D_T \grad T \right)
\f]
Where:
\vartable
T | Scalar field which is solved for, e.g. temperature
D_T | Diffusion coefficient
\endvartable
\heading Required fields
\plaintable
T | Scalar field which is solved for, e.g. temperature

Where:
\vartable
\vec{U} | Velocity

\vec{S}_U | Momentum source
\endvartable
\heading Required fields
\plaintable
U | Velocity [m/s]
