functionObject: change default behavior of 'end()' to do nothing rather than calling execute and write
Time: call functionObject 'execute()' and 'end()' for last time-step

Now the operation of functionObject 'end()' call is consistent between running and post-processing

Revert "functionObject: change default behavior of 'end()' to do nothing rather than calling execute and write"

This reverts commit 32e2e1bc.

functionObject: change default behavior of 'end()' to do nothing rather than calling execute and write

LduMatrix/SolverPerformance: Changed nIterations from label to labelType corresponding to the type solved

Now the number of iterations to solve each component in a segregated
solution are stored and returned in the SolverPerformance class.

OpenFOAM/containers/LinkedLists: Replaced partially specialized template classes with C++11 template aliases

This feature of C++11 avoids complex code duplication simplifies code maintenance

surfaceRegion will be the name of a class to provide support for surface
region selection.

SLList: now a C++11 template alias rather than a wrapper-class.

Now the specie reaction rates may be averaged over the entire domain or
a specified cellZone.

Renamed the original volRegion -> volFieldValue to clarify the purpose
of this class to process vol fields on a volRegion.

functionObjects::specieReactionRates: New functionObject to write the domain averaged reaction rates for each specie for each reaction

functionObjects: Further simplification and rationalization using the fvMeshFunctionObject base-class

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.

e.g.
    HashTable<label, string> table1
    {
        {"kjhk", 10},
        {"kjhk2", 12}
    };

    HashTable<label, label, Hash<label>> table2
    {
        {3, 10},
        {5, 12},
        {7, 16}
    };

Requires gcc version 4.7 or higher

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.

FixedList: Add constructors from iterators and C++11 initializer_list using C++11 constructor delegation

Test-List: Add demonstration of C++11 initializer list in conjunction with uniform initialization of vector

     List<vector> list5
     {
         {5, 3, 1},
         {10, 2, 2},
         {8, 1, 0}
     };

Improves stability for complex flows

The diameter of the drops formed are obtained from the local capillary
length multiplied by the \c dCoeff coefficient which defaults to 3.3.

omegaWallFunction: Improved low-Reynolds number behavior and consistency with the epsilonWallFunction

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.
