* Resolver for fast CSS typing. Handles abbreviations with the following
* notation:<br>
*
* <code>(-vendor prefix)?property(value)*(!)?</code>
*
* <br><br>
* <b>Abbreviation handling</b><br>
*
* By default, Emmet searches for matching snippet definition for provided abbreviation.
* If snippet wasn't found, Emmet automatically generates element with
* abbreviation's name. For example, <code>foo</code> abbreviation will generate
* <code><foo></foo></code> output.
* <br><br>
* This module will capture all expanded properties and upgrade them with values,
* vendor prefixes and !important declarations. All unmatched abbreviations will
* 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};
* -moz-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
* CSS property. For example, <code>-wm-float</code> will produce
*
* <pre><code>
* -webkit-float: ${1};
* -moz-float: ${1};
* float: ${1};
* </code></pre>
*
* Although this example looks pointless, users can use this feature to write
* cutting-edge properties implemented by browser vendors recently.
