CSSO, CSS Optimizer plugin for Metalsmith

New in 1.x

Updated to CSSO version 3.5.0
Updated to Metalsmith version 2.3.0
Changed testing framework to tape
Refactored tests to use temp directory for output to avoid flaky tests
Rudimentary support for source maps

Restructuring

To block CSSO from optimizing the structure of your CSS use the option restructure: false (default: true).

Source maps

Added rudimentary support for the CSSO option sourceMap: true (default: false) to generate corresponding source map files for each CSS file.

CSSO (CSS Optimizer) is a CSS minimizer unlike others. In addition to usual minification techniques it can perform structural optimization of CSS files, resulting in smaller file size compared to other minifiers.
