/**
 * If you want to interact with my mod you need to do it here.
 * 
 * There are only two ways to interact with my mod, but they are both very powerful:
 *  - You can either install your own module, which can swap out any of the dependencies
 *    or constants in my mod. You need to do this before the injector is created during
 *    preinit, so make sure this mod loads after yours and you do the installation before
 *    my mod does preinit.
 *    
 *  - You can request that your object is injected. My injector will try to fill any
 *    fields annotated @Inject with my objects. If you want to register your own ExGregilo
 *    link, then you need the LinkManager. You can get it using this interaction method
 *    by creating a class with a field such as "private @Inject LinkManager linkManager;"
 *    then creating an instance of that class and passing it to ExGregiloAPI.inject(yourClass);
 *    After this method executes on your class, your linkManager field will be populated
 *    (as well as all other fields with a valid injection target and annotation), and be
 *    ready to use for registering your own link or accessing other links. This method only
 *    works after preinit. Make sure you are using javax.inject.Inject for your annotation import.
 *    
 *  DO NOT TRY TO CREATE INSTANCES OF MY CLASSES. IT WILL NOT WORK. INTERACT WITH
 *  EXGREGILO USING ONLY THESE TWO METHODS. Thanks. - Q64
