Improve the log class again -!

#  ! /Usr/bin/ENV Python  #  -*-Coding: UTF-8 -*-  '''  Improved LOG classes: 1. if you use the format object, you do not need to collect Environment Information yourself. The database can collect information 2. bind multiple handler to a logger, and each handler sets the corresponding level of logs to generate multiple copies. Each handler only records its own level and contains logs higher than its own level. we still need the inspect library to collect environment information. Because the logging API is encapsulated, the format can only collect function information that directly calls the logging module API.
