Class
    Foam::histogramModels::unequalBinWidth

Description
    Histogram model which groups data into bins of unequal widths.

Usage
    Minimal example by using \c system/controlDict.functions:
    \verbatim
    histogram1
    {
        // Inherited entries
        ...

        // Mandatory entries
        ranges
        (
            // min       max
            (<scalar>    <scalar>)    // bin-0
            (<scalar>    <scalar>)    // bin-1
            ...
        );
    }
    \endverbatim

    where the entries mean:
    \table
      Property  | Description                       | Type   | Reqd | Deflt
      ranges    | Min-max values of histogram data <!--
                -->                 | List\<scalarMinMax\>  | no   | -
    \endtable

Note
  - All bins are half-open, that is [min, max).
  - Bins should be specified as consecutive, non-overlapping
    and adjacent intervals of the field variable. No warning
    or runtime error will be emitted, otherwise.
