✏️ /index_command.py

"""
Contains command classes which may interact with an index / the network.

Unlike its sister module, req_command, this module still uses lazy imports
so commands which don't always hit the network (e.g. list w/o --outdated or
--uptodate) don't need waste time importing PipSession and friends.
