Add Guides

[evilsoft]

We should have some Guides to address some of the terminology and theory used in this library.

The doumentation should provide the following guides

• [ ] Type Signatures
• [ ] Typeclasses (General information, methods and signature. Not so much laws)
• [ ] Natural Transformations (Just a brief summary, with very general language, not too much theory)
• [ ] Definitions of things like endomorphism, morphism, curry, etc
• [ ] Common Recipes

We have a layout from electric.js that we can use for tutorials. Here is the layout on our repo: https://github.com/evilsoft/crocks/blob/master/docs/src/layouts/tutorial.soy

It should look something like this: https://metaljs.com/docs/tutorials/tutorial-todo-jsx/before-we-start.html
