+Notes:
+ * The array `hist` has to be allocated and initialized with zeros before the first call to `PDAF_diag_histogram`
+ * The value of `delta` is >0 if the histogram is not flat. However, delta is not bounded and is hence difficult to interpret. 
+ * An example of using `PDAF_diag_histogram` can be found in the Lorenz-96 model example (see testsuite/src/lorenz96/compute_truermse.F90).
