// Module Name:
// - Commandline.h
//
// Abstract:
// - This is a helper class for representing a single commandline within the
//   Terminal Application. Users can specify multiple commands on a single
//   commandline invocation of the Terminal, and this class is used to represent
//   a single individual command.
// - Args are added to this class as wide strings, because the args provided to
//   the application are typically wide strings.
// - Args are retrieved from this class as a list of narrow-strings, because
//   CLI11 (which we're using to parse the commandlines) requires narrow
//   strings.
