Class
    Foam::functionEntries::includeFvConstraintEntry

Description
    Specify a fvConstraint dictionary file to include, expects the
    fvConstraint name to follow with option arguments (without quotes).

    Searches for fvConstraint dictionary file in user/group/shipped
    directories allowing for version-specific and version-independent files
    using the following hierarchy:
    - \b user settings:
      - ~/.OpenFOAM/\<VERSION\>/caseDicts/fvConstraints
      - ~/.OpenFOAM/caseDicts/fvConstraints
    - \b group (site) settings (when $WM_PROJECT_SITE is set):
      - $WM_PROJECT_SITE/\<VERSION\>/etc/caseDicts/fvConstraints
      - $WM_PROJECT_SITE/etc/caseDicts/fvConstraints
    - \b group (site) settings (when $WM_PROJECT_SITE is not set):
      - $WM_PROJECT_INST_DIR/site/\<VERSION\>/etc/caseDicts/fvConstraints
      - $WM_PROJECT_INST_DIR/site/etc/caseDicts/fvConstraints
    - \b other (shipped) settings:
      - $WM_PROJECT_DIR/etc/caseDicts/fvConstraints

    The optional field arguments included in the name are inserted in 'field' or
    'fields' entries in the fvConstraint dictionary and included in the name
    of the fvConstraint entry to avoid conflict.

    Examples:
    \verbatim
        #includeConstraint limitPressure(minFactor=0.1, maxFactor=2)
        #includeConstraint limitTemperature(min=101, max=1000)
    \endverbatim
    or for a multiphase case:
    \verbatim
        #includeConstraint limitLowPressure(min=1e4)
        #includeConstraint limitTemperature(phase=steam, min=270, max=2000)
        #includeConstraint limitTemperature(phase=water, min=270, max=2000)
    \endverbatim

    Other dictionary entries may also be specified using named arguments.
