Class
    Foam::functionObjects::cloudInfo

Group
    grpLagrangianFunctionObjects

Description
    This function object outputs Lagrangian cloud information to a file.  The
    current outputs include:
    - total current number of parcels
    - total current mass of parcels

    Example of function object specification:
    \verbatim
    cloudInfo1
    {
        type        cloudInfo;
        libs ("libcloudFunctionObjects.so");
        ...
        clouds
        (
            kinematicCloud1
            thermoCloud1
        );
    }
    \endverbatim


    \heading Function object usage

    \table
        Property     | Description             | Required    | Default value
        type         | type name: cloudInfo    | yes         |
        clouds       | list of clouds names to process |yes  |
    \endtable

    The output data of each cloud is written to a file named \<cloudName\>.dat
