ENH: LimitRange Function1 - extended and renamed

Description
    Function1 wrapper that maps the input value prior to it being used by
    another Function1.

    Example usage for limiting a polynomial:
    \verbatim
        <entryName>
        {
            type            inputValueMapper;
            mode            minMax;

            min             0.4;
            max             1.4;

            value polynomial
            (
                (5 1)
                (-2 2)
                (-2 3)
                (1 4)
            );
        }
    \endverbatim

    Here the return value will be:
    - poly(0.4) for x <= 0.4;
    - poly(1.4) for x >= 1.4; and
    - poly(x) for 0.4 < x < 1.4.

    Example usage for supplying a patch mass flux for a table lookup:
    \verbatim
        <entryName>
        {
            type            inputValueMapper;
            mode            function;

            function
            {
                type            functionObjectValue;
                functionObject  surfaceFieldValue1;
                functionObjectResult sum(outlet,phi);
            }

            value
            {
                type        table;
                file        "<system>/fanCurve.txt";
            }
        }
    \endverbatim

    Where:
    \table
        Property | Description                                  | Required
        mode     | Mapping mode (see below)                     | yes
        function | Mapping Function1                            | no*
        min      | Minimum input value                          | no*
        max      | Maximum input value                          | no*
        value    | Function of type Function1<Type>             | yes
    \endtable

    Mapping modes include
    - none     : the input value is simply passed to the 'value' Function1
    - function : the input value is passed through the 'function' Function1
                 before being passed to the 'value' Function1
    - minMax   : limits the input value to 'min' and 'max' values before being
                 passed to the 'value' Function1

Note
    Replaces the LimitRange Function1 (v2106 and earlier)
