addDefaultModules

Adds additional ModuleFactorys to the list of default factories that are added to each Tealium instance.

Each module added in this list will be added only if the same module wasn't already added in the specific config object. Generally factories added by default will not return any enforced settings, meaning that they will require some local or remote settings to initialize their respective modules.

If they contain some settings, instead, their modules will be initialized even if they are not configured elsewhere.
