/*
 * 'rem' is a Sass mixin that converts pixel values to rem values for whatever property is passed to it.
 * It returns two lines of code — one of the regular pixel values (for IE), and another with the
 * converted rem values (for everyone else). Special thanks to Chris Epstein (http://chriseppstein.github.com)
 * and Martin Bavio (http://martinbavio.com) for the help and code!
 * 
 * Sample input:
 * .element {
 *   @include rem('padding',10px 0 2px 5px);
 * }
