Possible error in example docs

[sheepman4267]

I should preface this by saying that I'm currently working on learning how to use django-markdownx for the first time, so I may just not know what I'm talking about.

That being said, I think there's at least one issue in the django admin section of the Example docs.
1: It seems to me that "MarkdowxModel" must be a typo.
2: While investigating the codebase and other docs to see if I was right, I discovered that I can't actually find anything by the name of MarkdownxModel. MarkdownxModelAdmin is there, as the example says it will be, but I'm really not sure from that example what "MarkdownxModel" would be referring to, even if it were spelled right.

Sorry if this is totally off-base.

Thanks!

Thank you. I think that should be Markdownx widget, not model.
