/*! \brief
* Data module for computing lifetime histograms for columns in input data.
*
* The input data set is treated as a boolean array: each value that is present
* (AnalysisDataValue::isPresent() returns true) and is >0 is treated as
* present, other values are treated as absent.
* For each input data set, analyzes the columns to identify the intervals
* where a column is continuously present.
* Produces a histogram from the lengths of these intervals.
* Input data should have frames with evenly spaced x values.
*
* Output data contains one column for each data set in the input data.
* This column gives the lifetime histogram for the corresponding data set.
* x axis in the output is spaced the same as in the input data, and extends
* as long as required to cover all the histograms.
* Histograms are padded with zeros as required to be of the same length.
* setCumulative() can be used to alter the handling of subintervals in the
* output histogram.
*
* The output data becomes available only after the input data has been
* finished.
