"Layout" should be "Typography" instead

[waldyrious]

The Layout examples page only deals with font sizes, whereas "layout" usually refers to the disposition of elements in the screen area (e.g. a column-based layout, the holy grail layout, etc.). This is partly acknowledged in the README, where those styles are referred to as "Font Layout".

Similarly, the layout.css file should be renamed typography.css, as well as other references.

This looks like a correct thing to do, I'll work on this :D
