device debug print helper
With the new default backend (not using thrust), it's not easy to print a single value or small range of values out of a device gtensor object.
Possible APIs:
- member function,
.host_view(...slice..), normal view if is host accessible, otherwise copies - free function,
gt::device_print(a, ...slice...)
one advantage of host_view type API, is it could be used in tests to avoid an explicit host vector declaration and copy.
