0.3 Performance improvements

• Significant peed improvements - most importantly utilizing
  multiple CPU-s (if available) to speed things up. On my 4-core
  box JsDuck is now even faster than ext-doc.
• Printing of performance info in verbose mode
• Support for comma-first coding style
• Few other fixes to JavaScript parsing

0.2 Most features of ext-doc supported

• Links from documentation to source code
• Syntax highlighting of code examples
• Tree of parent classes
• List of subclasses

0.1 Initial version

The very first version for the world to try.
