fvPatchFields/derived/fixedProfile: New BC which applies the specifie…

…d 1D profile

This is useful when applying an experimentally obtained profile as an
inlet condition:

    Example of the boundary condition specification:
    \verbatim
    myPatch
    {
        type            fixedProfile;
        profile    csvFile;

        profileCoeffs
        {
            nHeaderLine         0;          // Number of header lines
            refColumn           0;          // Reference column index
            componentColumns    (1 2 3);    // Component column indices
            separator           ",";        // Optional (defaults to ",")
            mergeSeparators     no;         // Merge multiple separators
            fileName            "Uprofile.csv";  // name of csv data file
            outOfBounds         clamp;      // Optional out-of-bounds handling
            interpolationScheme linear;     // Optional interpolation scheme
        }
        direction        (0 1 0);
        origin           0;
    }
    \endverbatim

or a simple polynomial profile:

    Example setting a parabolic inlet profile for the PitzDaily case:
    \verbatim
    inlet
    {
        type            fixedProfile;

        profile         polynomial
        (
            ((1 0 0)        (0 0 0))
            ((-6200 0 0)    (2 0 0))
        );
        direction       (0 1 0);
        origin          0.0127;
    }
    \endverbatim
