remove lswd test case, is tested in optimize.
tensor view can be done with less indeces than number of dimensions
added test for tensor view where number of indices is lower than number of dimensions
in original tensor

add pairwise_norm function for calculating the norm of two adjacent filter results
DOC minor
add function to calculate gradient for pairwise_norm
fix: pairwise_norm, add delta to gradient computation
reduce complexity of pairwise_norm, minor fix
added option for getting tensor_view with index_gen dim less than tensor dim
added test for tensor_view, when index_gen dim is less than tensor dim
enabled pairwise_norm for last dim
added test for pairwise_norm last dim
