default whern surface does not support volumeType.

BUG: conformalVoronoiMesh.  Making test "totalHits >= hitLimit" rather than
"totalHits = hitLimit" to be strictly consistent and always trigger
the iteration termination message.

from dictionary and using from controls object.

position of patch points.  Adding autoMap and rmap functions to
correctly handle p0 on decomposition and reconstruction.

the surface and not on an edge or point, do not check that the line
between the sample and the nearest point is parallel to the normal.

No longer reading or writing edgeDirections - calculating them on
read.

Properly initialising data in featureEdgeMesh constructor.

Fixing use of extend for treeBoundBox.

Removing writeObj from featureEdgeMesh constructor - calling
explicitly from surfaceFeatureExtract.

So now we can read multiple times (using UIPstream) from PstreamBuffers
    PstreamBuffers pBufs
    UIPstream str1(procI, pBufs);
    str1>> ..
    UIPstream str2(procI, pBufs);
    str1>> ..

an 0.001.

Useful for in parallel if it cannot find processor*/constant/polyMesh/points
and decides to read undecomposed constant/polyMesh/points...

- removed globalPointPatch*
- removed pointPatchInterpolate*
since all is now inside volPointInterpolation.

- use .obj files for debugging purposes instead.

- operator[] with label -> get args at index
- operator[] with word  -> get named option

- also update links from opencfd.co.uk -> openfoam.com

- deprecate argList::additionalArgs() method and remove uses of it

- also provide size() method, which returns the number of arguments

- make centrally available via #include "addOverwriteOption.H"
