device_ptr is a pointer-like object which points to an object that resides in memory associated with the device system.
device_ptr has pointer semantics: it may be dereferenced safely from anywhere, including the host, and may be manipulated with pointer arithmetic.
device_ptr can be created with device_new, device_malloc, device_malloc_allocator, device_allocator, or device_pointer_cast, or by explicitly calling its constructor with a raw pointer.
The raw pointer contained in a device_ptr may be obtained via get member function or the raw_pointer_cast free function.
Algorithms operating on device_ptr types will automatically be dispatched to the device system.
device_ptr is not a smart pointer; it is the programmer's responsibility to deallocate memory pointed to by device_ptr.
