If you add a content field to a model named og_title, it will use that as the default for for the Open Graph meta title, and Twitter Card meta title. If a customer does not, it will default to the models meta title, which exists for every model with a view and route. If the customer wants a specific Twitter Card meta title, they can create a content field named tc_title on the model. NOTE: this will only apply to Twitter card, and will not default to Open Graph. If only tc_title exists, the Open Graph title will still default to the meta_title.
