 * be automatically transformed into <code>property-name: ${1}</code> snippets. 
 * 
 * <b>Vendor prefixes<b><br>
 * 
 * If CSS-property is preceded with dash, resolver should output property with
 * all <i>known</i> vendor prefixes. For example, if <code>brad</code> 
 * abbreviation generates <code>border-radius: ${value};</code> snippet,
 * the <code>-brad</code> abbreviation should generate:
 * <pre><code>
 * -webkit-border-radius: ${value};

 * border-radius: ${value};
 * </code></pre>
 * Note that <i>o</i> and <i>ms</i> prefixes are omitted since Opera and IE 
 * supports unprefixed property.<br><br>
 * 
 * Users can also provide an explicit list of one-character prefixes for any

 * 
 * <pre><code>
 * -webkit-float: ${1};
 * -moz-float: ${1};
 * float: ${1};
 * </code></pre>
 *
