Class
    Foam::binModels::singleDirectionUniformBin

Description
    Calculates binned data in a specified direction.

    For example, a 10cm-long patch extending only in the x-direction
    can be binned into 5 bins in the same direction, so that
    local information can be output for each 2cm-long segment.

Usage
    Minimal example by using \c system/controlDict.functions:
    \verbatim
    binField1
    {
        // Other binField entries
        ...

        // Mandatory entries
        binModel          singleDirectionUniformBin;

        binData
        {
            // Mandatory entries
            nBin          <label>;
            direction     <vector>;

            // Optional entries
            cumulative    <bool>;
            min           <scalar>;
            max           <scalar>;
        }
    }
    \endverbatim

    where the entries mean:
    \table
      Property  | Description                           | Type   | Reqd | Deflt
      binModel  | Type name: singleDirectionUniformBin  | word   | yes  | -
      binData   | Entries of the chosen bin model       | dict   | yes  | -
      nBin      | Number of bins in binning direction   | label  | yes  | -
      direction | Binning direction                     | vector | yes  | -
      cumulative | Flag to bin data accumulated with increasing distance <!--
                --> in binning direction                | bool   | no   | false
      min       | Min-bound in the binning direction with respect to   <!--
                --> the global coordinate system's origin | scalar | no | GREAT
      max       | Max-bound in the binning direction with respect to   <!--
                --> the global coordinate system's origin | scalar | no | GREAT
    \endtable
