Registering your module is done through the
method call. That method accepts two parameters: the name of your module class
and an associative array of information for building your settings form.
The settings array is a nested set of information that allows you to define tabs, sections within your tabs and fields within your sections. The top-level array items should be associative arrays with the slug for the tabs as the array keys. The title of the tabs should also be defined within these arrays as shown in the example below.
Within your tab arrays should be another array that defines your sections, with the slug for the sections as the array keys. The title of the sections should also be defined within these arrays, as shown in the example below.
Within your section arrays should be another array that defines your fields, with the slug for the fields as the array keys. Please see the Settings Field Reference for an in-depth look at all of the field types as well as additional configuration properties.
Note that the slug for tabs, sections and fields should be unique or you will
run into conflicts. For example, you will run into issues if you have two tabs
that use the slug
