Need for App ID flag

[hudson-pierce]

Feature Request

Currently the app that gets created by cordova-paramedic has a default app ID of io.cordova.hellocordova. Unfortunately, there is currently no flag that allows the user to specify a different app ID via the CLI.

Motivation for Feature

For instance, in my use case I need to specify a specific app ID since the plugin under test requires a license key that is tied directly to the app ID.... It would be much appreciated if such a flag could be added.
