Details: - Relaxed the constraint in bli_obj_attach_buffer_check(), which required the buffer address being attached to be non-NULL. This is acceptable because the user was already able to create and use objects with NULL buffers (via bli_obj_create_without_buffer(), which initializes the buffer to NULL). - Inserted calls to newly defined function, bli_check_object_buffer(), into nearly all operations' _check() or _int_check() functions. This allows BLIS to abort peacefully if a computational routine is called with an object containing a NULL buffer. By contrast, under such conditions, BLAS would typically fail with a segmentation fault. - Within operation front-ends, moved the calls to _check()/_int_check() so that zero dimensions are checked first (and if found, execution returns with trivial or no computation). This resolves issue #7. Thanks to Jack Poulson for reporting this bug.
