25 * Implementation of the Wald-Wolfowitz runs test for 2D histograms.\n
26 * This class is derived from the abstract class JTest_t(). For a general description of the implementation of this and other tests derived from JTest_t(), see its documentation.\n
27 * The parameter `slice` can have the values x, X, y or Y. The histograms are sliced along the corresponding axis, and the runs test is applied to each slice.\n
28 * This test uses the input parameter `threshold` to evaluate whether the test is passed or failed for each slice.\n
29 * The evaluation is done by comparing the threshold value with the result of the runs test.\n
30 * The results for each slice are stored in the results buffer (see JTest_t())
