Class
    Foam::functionObjects::readFields

Description
    Reads fields from the time directories and adds them to the mesh database
    for further post-processing.

    Example of function object specification:
    \verbatim
    readFields1
    {
        type        readFields;
        libs        ("libfieldFunctionObjects.so");
        ...
        fields
        (
            U
            p
        );

Usage
    \table
        Property     | Description             | Required    | Default value
        type         | type name: readFields   | yes         |
        fields       | list of fields to read  |  no         |
    \endtable
