initial commit of the various get-started partials/templates
Create handlebars helpers to assist with get-started bootstrapping

* `setCustomGridFont` => generates CSS based on selected font
* `length` => gives the length of an array.
* `setGridClasses` => generates class names based on mediaquery array
remove row.handlebars from templates/ root dir
Improve route handler

* Generate grid CSS server-side
* convert short-hand media query into full media query
* Comment out expose() methods for now
set up start.handlebars server-side
initial commit for get-started css
Simplify class names, and correct handlebars variable paths

remove setCustomGridFont helper, and create a partial instead
only show path to grid.css if it contains a value
remove `length` helper, use std. grid class names instead
Fix a few bugs in the handlebars logic

* Put the generated CSS inside a `<style scoped>` block
* Give class names to the sections that render fonts/grid rules
so that they can be updated on the client.
