Wrapper Execution Trace Logs

It is possible to log the execution traces of wrappers, both of wrappers which are deployed in the Wrapper Server and of wrappers executed from the Wrapper Generation Tool. Logging can be enabled globally for all wrappers, or just for specific ones. The user can choose between logging all the executions of the same wrapper into the same log file, and logging each execution separately to different files, where each file name is distinguished by the start date and an identifier of the execution.
