Document the RichTextFX equivalent API of corresponding Swing rich text editor API

[JordanMartinez]

Coming from this comment

To give some context to this, I'm coming here from the Swing world (pity me), so I'm essentially looking for specific features in RichTextFX that are available within JTextComponentand Document (or more specifically how I can implement them myself).

and my suggestion

Perhaps we should include a table in the wiki that shows new users of this project what the JavaFX counterpart in RichTextFX is for a Swing API? It may also help us in knowing what other features could be implemented in this project.

We should add a page to the wiki that shows a table of equivalent API, as started/demonstrated here
