  36  * \brief
  37  * Tests for functionality of analysis data histogram modules.
  38  *
  39  * These tests check that classes in histogram.h compute histograms correctly
  40  * with simple input data.  Also different ways of initializing the histograms
  41  * are tested.
  42  * Checking is done using gmx::test::AnalysisDataTestFixture and reference
  43  * data.  Also the input data is written to the reference data to catch
  44  * out-of-date reference.
