Collects and writes case information to file in OpenFOAM dictionary or JSON
format.  Data includes:

- meta: case name, path, regions, parallel etc.
- dictionaries: entries retrieved from dictionaries - registered or from file
- per region: mesh metrics, boundary and boundary field types
- function object results

Example of function object specification:

    caseInfo
    {
        type            caseInfo;
        libs            (utilityFunctionObjects);

        // Warn when entries are not found
        lookupMode  warn; // none | warn | error;

        // Write format
        writeFormat json; //  dictionary | json;

        dictionaries
        {
            USolver // User-specified names
            {
                // Look up using registered name
                name        "fvSolution";

                // Optionally limit to specific entries
                include
                (
                    "solvers/U/solver"
                );
            }
            fvSchemes
            {
                name        "fvSchemes";

                // include all entries by default
            }
            timeScheme
            {
                name        "fvSchemes";

                include
                (
                    "/ddtSchemes/default"
                );
            }

            turbulence
            {
                name        "turbulenceProperties";

                // include all entries by default
            }
            controlDict
            {
                // Look up using file path
                path        "<case>/system/controlDict";

                include
                (
                    "application"
                    "deltaT"
                    "startTime"
                    "endTime"
                );
            }
        }

        functionObjects (minMax1);
    }
