Create a Sassy component library

@egillespie Can you take a look at this? It's hosted here and meets the following criteria:

• All components in this HTML are styled using Sass
• Use four colors from a random color palette (just copy the hex values into your Sass file) and link to your palette in the HTML
• Font sizes are all determined by one base font size variable, even in input and textarea elements, and headings are all differently sized
• All text uses the same font family, even in input and textarea elements
• Elements shaped like a box (img, input[type="text"], textarea) have the same border-radius
• At least one built-in Sass function is used to style a component
• Variables are defined in their own Sass file
• Sass files are saved in a source directory and CSS files are saved in a compiled directory
• A source map for your component library is included in the project
