Dear Readers,

Please find in the package two items, i.e. 
"supplementary_note.pdf" and "video.mp4" . 

"supplementary_note.pdf" is a supplementary note.  It documents
the details that didn't get the chance to be presented in the paper.

"video.mp4" is a video for the demonstration of our paper.

Yours faithfully,
Wang Zhenni
