Instances of this class are private to work items, and allow sharing of private data across different parallel_for_work_item calls.

                                                                                                                                                                                                                                              Use COMPUTECPP_PRIVATE_MEMORY_ATTR attribute to ensure that the private memory class is allocated in the private address space. By default, a variable declared in a parallel_for_work_group will be allocated in the local address space
