This was going wrong in a fair few cases where you would get regions which
were delimited by a combination of intersections with unnamed surfaces (wall)
and named surfaces (faceZone surface) but not with either of these sets
individually. This would cause there to be unvisited cells (zone = -2)
next to a visited cells but separated by a named surface only (and not an
unnamed surface). Fixed by using direct surface intersection in the removal
part. Related to #66.
Now the functionality to write single graph files or log files (vs time)
may be used in the creation of any form of functionObject, not just
those relating to a mesh region.
The change from C++0x to C++11 allows all of C++11 functionality to be
used in OpenFOAM, in particular constructor delegation which avoids code
duplication or constructor helper functions. However, this also means a
change to the minimum gcc version supported which is now 4.7 rather than
4.5.
Note that gcc-4.7 does not support the entire C++11 standard but does
support all of the functionality currently needed for further OpenFOAM
development. The minimum gcc-version which supports the entire C++11
standard is 4.8 which is now the recommended minimum gcc version.
The diameter of the drops formed are obtained from the local capillary
length multiplied by the \c dCoeff coefficient which defaults to 3.3.

Changed default mode of operation to use standard y+ based switching
rather than the previous ad hoc blending and added consistent handling
of the near-wall generation term.
This boundary condition provides a wall constraint on turbulnce specific
dissipation, omega for both low and high Reynolds number turbulence models.
The near-wall omega may be either blended between the viscous region and
logarithmic region values using:
\f[
\omega = sqrt(\omega_{vis}^2 + \omega_{log}^2)
\f]
where
\vartable
\omega_{vis} | omega in viscous region
\omega_{log} | omega in logarithmic region
\endvartable

or switched between these values based on the laminar-to-turbulent y+ value
derived from kappa and E. Recent tests have shown that the standard
switching method provides more accurate results for 10 < y+ < 30 when used
with high Reynolds number wall-functions and both methods provide accurate
results when used with continuous wall-functions. Based on this the
standard switching method is used by default.
