/**
* @brief Utl initializer class. Solves the problem with ordering of
* constructors & destructors.
*
* The h file needs to be included in:
* - all cpp files whose static members are initialized in UtlInit constructor,
* in order to make sure they are initialized properly whenever they are linked
* into program.
* - it also has to be included as the first include in cpp files, that
* initialize static members whose constructor or destructor tries to use any
* static members we initialize here.
