Class
    Foam::functionObjects::writeObjects

Description
    Allows specification of different writing frequency of objects registered
    to the database.

    It has similar functionality as the main time database through the
    \c writeControl setting:
      - timeStep
      - writeTime
      - adjustableRunTime
      - runTime
      - clockTime
      - cpuTime

    It also has the ability to write the selected objects that were defined
    with the respective write mode for the requested \c writeOption, namely:
    \vartable
        autoWrite | objects set to write at output time
        noWrite   | objects set to not write by default
        anyWrite  | any option of the previous two
    \endvartable

    Example of function object specification:
    \verbatim
    writeObjects1
    {
        type            writeObjects;

        libs            ("libutilityFunctionObjects.so");

        objects         (obj1 obj2);
        writeOption     anyWrite;
    }
    \endverbatim

Usage
    \table
        Property     | Description             | Required     | Default value
        type         | type name: writeObjects | yes          |
        objects      | objects to write        | yes          |
        writeOption  | only those with this write option | no | anyWrite
    \endtable

    Note: Regular expressions can also be used in \c objects.
