surfaceFeatures: New version of surfaceFeatureExtract with simplied controls

Browse Source 
Surfaces are specified as a list and the controls applied to each, e.g. in the
rhoPimpleFoam/RAS/annularThermalMixer tutorial:

    surfaces
    (
        "AMI.obj"
        "shaft.obj"
        "wall.obj"
        "statorBlades.obj"
        "rotorBlades.obj"
    );

    includedAngle   150;  // Identifes a feature when angle
                      // between faces < includedAngle
    trimFeatures
    {
        minElem         10;   // minimum edges within a feature
    }

    writeObj        yes;  // writes out _edgeMesh.obj files to view features

If different controls are required for different surfaces multiple
sub-dictionaries can be used:

    AMIsurfaces
    {
        surfaces
        (
            "AMI.obj"
        );

        includedAngle   140;  // Identifes a feature when angle
                          // between faces < includedAngle
        trimFeatures
        {
            minElem         8;   // minimum edges within a feature
        }

        writeObj        yes;  // writes out _edgeMesh.obj files to view features
    }

    otherSurfaces
    {
        surfaces
        (
            "shaft.obj"
            "wall.obj"
            "statorBlades.obj"
            "rotorBlades.obj"
        );

        includedAngle   150;  // Identifes a feature when angle
                          // between faces < includedAngle
        trimFeatures
        {
            minElem         10;   // minimum edges within a feature
        }

        writeObj        yes;  // writes out _edgeMesh.obj files to view features
    }

Existing feature edge files corresponding to particular surfaces can be specified using
the "files" association list:

    surfaces
    (
        "AMI.obj"
        "shaft.obj"
        "wall.obj"
        "statorBlades.obj"
        "rotorBlades.obj"
    );

    files
    (
        "AMI.obj" "constant/triSurface/AMI.obj.eMesh";
    );

    includedAngle   150;  // Identifes a feature when angle
                      // between faces < includedAngle
    trimFeatures
    {
        minElem         10;   // minimum edges within a feature
    }

    writeObj        yes;  // writes out _edgeMesh.obj files to view features
