     !important properties: my Bool %important{Str} = $css.important();
   - issue #5 don't inherit relative quantities, e.g. 'font-size: 1.5em'.
     generally these shouldn't be propagated and re-applied.
   - also add .parent() attribute and .inherited method to make it easier
     for agents to do their own inheritance.
   - issue #6 - fix optimization of 'inherit' and 'initial' component properties

      This: border:5pt solid; border-color:red green blue yellow;
      Was optimized to: border:5pt solid red green blue yellow;
      Which is a step too far. The optimize() method now leaves the
      above alone. The general rule is that a property with multiple
      terms won't be further optimized.

0.1.1 Added `.optimize` method. For direct optimization of ASTs, without
      the need to create intermediate objects
0.1.0 Improved write optimizations
      For example now rewrites style: margin-top: 1pt; margin-right: 2pt;
      as "margin:1pt 2pt"
0.0.4 CSS::Declarations:
     - allow list assignment. E.g.: $css.new: :background-position<top left>;
       shortcut for: $css.new: :background-position("top left");

      -- text-align is 'left' or 'right' depending on direction
      (See README.md Properties appendix)
