Absence of a add_module command

[Javiery3889]

Based on the UG, there is a delete_module command as shown below:

However, there is no add_module command in the UG as such it was slightly unclear how a user can add a module in the product. Instead, a module can be added using the add_class command as shown below:

Perhaps it would be better to emphsise in the command description that the add_class command also adds a module to the product if it does not exist.

Another suggestion would be to separate the addition of class and module to improve clarity, since the commands for class and module deletion are separated into delete_class and delete_module respectively.
