[spp] [PATCH 3/3] spp: change logger to optional

[ogawa.yasufumi@lab.ntt.co.jp]

From: Yasufumi Ogawa <ogawa.yasufumi@lab.ntt.co.jp>

Logger in spp.py is used only for debugging and useless for users.

Use of logger is selectable by comment/uncomment logger's setting
defined after importing libraries.
