SINGA-186 Create Python Tensor class

- Add numpy.i in src/python/swig
  . core_tensor.i is revised to include it
  . GetValue method is added in singa::Tensor class (tensor.h)
  . in tensor.py, the member methods are added to get/set numpy array from/to tensor data
     . copy_from_numpy, which calls singa::Tensor::CopyDataFromHostPtr
     . copy_to_numpy, which calls singa::Tensor::GetValue
  . also global functions are added
     . from_numpy
     . to_numpy

NOTE: numpy.i is downloaded from https://github.com/numpy/numpy/tree/master/tools/swig

TODO: unittest_python.py

> This ticket would add a Python Tensor class, which provides functions as the C++ Tensor
class with APIs in Python convention. Most of these functions are implemented by calling the
C++ Tensor functions via Swig.
