b790a69507 DimensionedFunction1: Permit setting argument-dimensions of inline functions
Both argument and value dimensions can be set for inline-constructable
function1-s. For example, this inline table function:

    massFlowRate table [CAD] [g/s]
    (
        (0 0.46)
        (0.17 1.9)
        (0.31 4.8)
    );

Is equivalent to this dictionary specification:

    massFlowRate
    {
        type    table;
        xDimensions [CAD];
        dimensions [g/s];
        values
        (
             (0 0.46)
             (0.17 1.9)
             (0.31 4.8)
        );
    }

In the inline form, the argument/x-dimensions come first, and the value
dimensions second. If there only one dimension set provided, then this
is assumed to be the value dimensions.

bf044f5c47 DimensionedFunction1: Function1 with dimensions
This can be used identically to a standard Function1. In addition, it
also permits specification of the dimensions. This allows the dimensions
to be checked. It also permits unit conversions. For example:

    <name>
    {
        type        table;

        // Dimensions
        xDimensions [CAD];  // Optional. Argument dimensions/units.
                            // Here, this specifies coordinates are in
                            // crank angle degrees (available if using
                            // engine time).
        dimensions  [mm];   // Optional. Value dimensions/units.
                            // Here, values are in mm.

        // Tablulated data
        values
        (
            (0 0)
            (60 12)         // <-- i.e., 12 mm at 60 degrees
            (180 20)
            (240 8)
            (360 0)
        );
        outOfBounds repeat;
    }

This replaces TimeFunction1, as it allows per-function control over
whether the function is considered to be one of real-time or user-time.
