This PR does the following:
- improvement: dramatic reduce of the call to _is_batch_set
- bugfix: list(Batch()) fail; Batch(a=[torch.ones(3), torch.ones(3)]) fail;
- misc: add type check for each element rather than the first element; add test case; _create_value with torch.Tensor does not have np.object type;
* in-place empty_ for Batch
* change Batch.empty to in-place fill; add copy option for Batch construction
* type signiture & remove shadow names for copy
* add doc for data type (only support numbers and object data type)
* add unit test for Batch copy
* fix pep8
* add test case for Batch.empty
* doc fix
* fix pep8
* use object to test Batch
* test commit
* refact
* change Batch(copy) testcase
* minor fix
