    public class ArrayHistogramRanges
extends AbstractArrayProvider
    Outputs the ranges generated by adams.data.statistics.ArrayHistogram using the incoming double array or matrix.
    In case of an array, the data-type and location are ignored.

    Input/output:
    - accepts:
       java.lang.Double[]
       java.lang.Double[][]
    - generates:
       java.lang.String


    -logging-level <OFF|SEVERE|WARNING|INFO|CONFIG|FINE|FINER|FINEST> (property: loggingLevel)
    The logging level for outputting errors and debugging output.
    default: WARNING

    -skip <boolean> (property: skip)
    If set to true, transformation is skipped and the input token is just forwarded 
    as it is.
    default: false
 
    -stop-flow-on-error <boolean> (property: stopFlowOnError)
    If set to true, the flow execution at this level gets stopped in case this 
    actor encounters an error; the error gets propagated; useful for critical 
    actors.
    default: false
 
    -silent <boolean> (property: silent)
    If enabled, then no errors are output in the console; Note: the enclosing 
    actor handler must have this enabled as well.
    default: false
 
    -output-array <boolean> (property: outputArray)
    If enabled, the ranges are output as array rather than one by one.
    default: false
 
    -type <ROW_BY_INDEX|COLUMN_BY_INDEX> (property: dataType)
    In case of a double matrix, whether to retrieve rows or columns; ignored 
    in case of simple double arrays.
    default: COLUMN_BY_INDEX
 
    -location <adams.core.base.BaseString> [-location ...] (property: locations)
    The locations of the data; An index is a number starting with 1; the following 
    placeholders can be used as well: first, second, third, last_2, last_1,

    -bin-calc <MANUAL|FREQUENCY|DENSITY|STURGES|SCOTT|SQRT> (property: binCalculation)
    Defines how the number of bins are calculated.

    default: 1.0
    minimum: 1.0E-5
 
    -normalize <boolean> (property: normalize)
    If set to true the data gets normalized first before the histogram is calculated.
    default: false
 
    -use-fixed-min-max <boolean> (property: useFixedMinMax)
    If enabled, then the user-specified min/max values are used for the bin 
    calculation rather than the min/max from the data (allows comparison of 
    histograms when generating histograms over a range of arrays).
    default: false
 
    -manual-min <double> (property: manualMin)
    The minimum to use when using manual binning with user-supplied min/max 
    enabled.
