The InitializeICU class loads and initializes data items that are required

internally by various ICU functions. It makes sure that ICU function u_init

is only called once by a process. A module which is using ICU APIs needs

to call InitializeICU::initICUSuccessful first before it calls other ICU

APIs. If InitializeICU::initICUSuccessful is failed, the module should not

call other ICU APIs.
