Say I have a command named command that accepts top-level flags (say -a & -b).
How can I share the Bool value for each flag from the Command: ParsableCommand to Subcommand1: ParsableCommand, Subcommand2: ParsableCommand, etc.
e.g.:
command -a subcommand1
The Subcommand1 Swift code needs to know that Command.a == true but Command.b == false.
