    3. Added tests for 0d data for all functions.
    4. Added tests for different modes in sp data type.
18. test_mo_poly, converted
    1. Added test for the evaluation of point at the vertex.
19. test_mo_sce, converted
    1. Added SCE test for griewank function.
20. test_mo_spatialsimilarity, converted
    1. Only changed to pFUnit assertion.
21. test_mo_standard_score, converted

22. test_mo_string_utils, converted
    1. Only changed to pFUnit assertion.
23. test_mo_temporal_aggregation, created
    1. Monthly average calculation for daily data.
    2. Hourly average calculation for hourly data.
    3. Optional input for missing value substitute untested.
24. test_mo_timer, converted
    1. Removed timer printout.
    2. Perform simple time sanity check.
25. test_mo_utils, converted
    1. Only changed to pFUnit assertion.
    2. Since mo_utils has many functionality as logical operators, most assertion used are simple logical, i.e. assertTrue() and assertFalse()

    1. Only changed to pFUnit assertion.

Modules:

1. mo_append, modified
   1. Added function append_i4_3d for the append() interface.
2. mo_percentile, modified
   1. Fixed a typo in the module function n_elements() so that masking works properly.

   1. Implemented a fix by Mathias Cuntz to solve overflow on RNG.
