When a comments get created, the package can transform that comment for you. This can be handy when you're allowing the user to use markdown to render comments, but you want to display them as HTML.
A comment can be created like this:
$blogPost->comment('Everybody saw the sunshine');
The text passed to comment used as the value of the original_text attribute of the Comment model.
In the comments config, you can specify comment transformer classes that can transform the comment. The transformed comment will be put in the text attribute of the Comment model. If you're building a UI, you should use text to display the comment, and the original_text when the user is editing the comment.
