No progress to file

Summary

All progress logs are filtered when cout is not interactive.

Rationale

This is the implementation of issue #1780 (closed).

Implementation Details

Classes and files

In a nutshell:

• a wrapping of isatty() has been added in otb::System, with an implementation for Windows
• the 3 watchers have been modified to filter progress messages on non-interactive cout:
  • StandardFilterWatcher
  • StandardOneLineFilterWatcher
  • StandardWriterWatcher

The messages are only print at the end of processing.

Additional notes

TODO:

• check if there is a mechanism to dump the content of watcher after a processing is interrupted.
