 /**
  * Minify a CSS string
  * 
  * @param string $css
  * 
  * @param array $options available options:
  * 
  * 'preserveComments': (default true) multi-line comments that begin
  * with "/*!" will be preserved with newlines before and after to
  * enhance readability.
  * 
  * 'prependRelativePath': (default null) if given, this string will be
  * prepended to all relative URIs in import/url declarations
  * 
  * 'currentDir': (default null) if given, this is assumed to be the
  * directory of the current CSS file. Using this, minify will rewrite
  * all relative URIs in import/url declarations to correctly point to
  * the desired files. For this to work, the files *must* exist and be
  * visible by the PHP process.
  *
  * 'symlinks': (default = array()) If the CSS file is stored in 
  * a symlink-ed directory, provide an array of link paths to
  * target paths, where the link paths are within the document root. Because 
  * paths need to be normalized for this to work, use "//" to substitute 
  * the doc root in the link paths (the array keys). E.g.:
  * <code>
  * array('//symlink' => '/real/target/path') // unix
  * array('//static' => 'D:\\staticStorage')  // Windows
  * </code>
  * 
  * @return string
