- make the purpose more explicit, and reduces some work for the
  compiler as well.

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.

to simplify writing common functionObjects and avoid unnecessary code duplication

  - Avoids the need for the 'OutputFilterFunctionObject' wrapper
  - Time-control for execution and writing is now provided by the
    'timeControlFunctionObject' which instantiates the processing
    'functionObject' and controls its operation.
  - Alternative time-control functionObjects can now be written and
    selected at run-time without the need to compile wrapped version of
    EVERY existing functionObject which would have been required in the
    old structure.
  - The separation of 'execute' and 'write' functions is now formalized in the
    'functionObject' base-class and all derived classes implement the
    two functions.
  - Unnecessary implementations of functions with appropriate defaults
    in the 'functionObject' base-class have been removed reducing
    clutter and simplifying implementation of new functionObjects.
  - The 'coded' 'functionObject' has also been updated, simplified and tested.
  - Further simplification is now possible by creating some general
    intermediate classes derived from 'functionObject'.

functionObjectFile provides basic directory, file and formatting functions
functionObjectFiles provides multi-file cache

Class now provides helper functions to generate files on-the-fly by
function objects, as opposed to attempting to control all files needed
by the function object (earlier implementation lead to over-complication
and was error prone)

Removed unused dependencies on CGAL

Also, 2011 copyright dates.

when required, rather than looking up from dictionary every time.

Added relaxationModel and faceAreaWeightModel runTime selectable models.
