Implementing ability to add/remove key from agent in
InspectPrivateKeyDialog, although removing it from the agent
should give a warning that logging in to a remote server such as
MASSIVE will prompt the Launcher to re-add the key to the agent
at least for the lifetime of that Launcher session.
Starting to encapsulate logging functionality in its own class.
This new Logger class still isn't being actively used, but the
aim is get rid of the global logger variables from utilityFunctions.
Not importing configureLogger from utilityFunctions.
Deleted, and replaced by InspectKeyDialog.py
Deleted, and replaced by logger/Logger.py
Added __init__.py so we can import logger subdirectory as module.
