useful C++ classes and routines used by Martchus' applications

 Martchus-cpp-utilities is a library that contains helpers for:
   * parsing command-line arguments and providing Bash completions
   * working with dates and times
   * converting primitive data types to byte-buffers, and vice versa
   (eg, between litte-endian and big-endian)
   * common string conversions/operations
   * using standard IO streams
   * using SFINAE by providing additional traits (eg, for checking whether a
   type is iteratable)
   * testing with *CppUnit*
   * CMake, with convenient modules and templates
 .
 It also provides the following convenience functions and data structures:
   * min() and max(), for any number of arguments
   * digitsum(), factorial(), powerModulo(), inverseModulo(), and orderModulo()
   * Damerau–Levenshtein distance
   * *N*-dimensional arrays
