Add Fomantic vs Semantic explanation

[douglasg14b]

There should be a section above the ToC that provides an explanation of what this fomantic thing is about.

It should answer these questions:

• What is Fomantic?
• Why was it made?
• Should I use it instead?

This will probably be under a section:

Fomantic?

--write stuff here--

Pinging @hammy2899

I feel like you are better qualified to define the answers to those questions (Or write a piece for that section) for a description than I am.
