Initial commit containing Marc's pass at Whipcrack (see him for a verbal change-log).
Added empty README files into empty directories to get them into the repo, and to serve as a place to eventually provide documentation for those directories, if we see fit.
Pulled helper classes out of base.sass, into their own helpers.sass file, and added an import rule to main.sass to account for this new file.
Adjusted the primary Sass README to account for the helper classes moving out of base.sass and into their own file. Also, a bit of formatting clean-up.
Formatting clean-up.
A recompiled .css file.
Added the .md extension to the README files, and quickly created an new, empty one for the project's root.
Looks like I forgot to get this file into the repo, until now.
Made a mixin for buttons (see commit details)

1. Moved the .btn class out of base.sass and into its own mixin file (button.sass)
2. Converted it from a class to a mixin
3. Made many parameters
4. Wrote up instructions and two usage examples
5. Added the new mixin file to an @import statement in main.sass
README adjustments (see commit details)

1. Removed the README.md files from all of /sass/'s child directories
2. Updated the README.md file at /sass/README.md
Added the .c class, provided an example HTML element structure, and clarified the max-width variable name.
Tightened up the grid spacing rules, and extended them so their value(s) changed based on viewport width.
Since the selection-type variable was set to the same hex color value as base-font-color, I made selection-type equal to the base-font-color variable, rather than re-use the hex color value a second time.
Tightened up the left padding rules for ol, ul, and dd elements.
Discovered that we weren't yet defining a font-stack for our elements; fixed that.
A rough first-pass at creating a demo-document.
The compiled stylesheet.
Added quite a bit more to the demo-document.
Gave the block quote element a bit of left margin.
A recompiled css file.
