approved.

Should this now be showing up in the reference, and have nav pane
entries?

Summary: First pass at <mixin>

New Features: <mixin>

Bugs Fixed:
LPP-2302  Implement LZX <mixin> tag
LPP-7365 Update color names to use CSS3 standard

Technical Reviewer: max (pending)
QA Reviewer: hminsky (pending)
Doc Reviewer: [EMAIL PROTECTED] (pending)

Documentation:

   <mixin> is like <class> but rather than creating something you can
   instantiate, creates a template that can be 'mixed in' (added to)
   more than one other class.  A <mixin> is like an interface, but it
   is allowed to have state and implementation.

   <mixin> is an advanced feature.  To add a mixin to a class you
   say:

   <class name="icecream" ... />
   <class name="walnuts" ... />

   <mixin name="toppings">
     <attribute name="sauce" type="color" value="lavender" />
     <attribute name="whippedcream" type="boolean" value="true" />
     <attribute name="cherry" type="boolean" value="true" />
     ...
   </mixin>

   <class name="sundae" extends="icecream" with="toppings />

   <sundae name="chocfulla"
     flavor="honeydew"
     sauce="lemonchiffon">
     <walnuts ground="true" />
   </sundae>

   See tests/classes.lzx for a more complete example

Details:
   test/classes: Create a more complex example using classes and
   mixins

   lfc-undeclared: Add <mixin>

   LzConstants, ViewSchema: Update color tokes to CSS3 standard

   ClassCompiler: Learn how to create interstitial <nodes>, insert
   them into the schema.

Compiler, MixinCompiler: For now, just compiles the mixin as a class.

   NodeModel: Only classes can have `extends` or `with` attributes.

   ElementWithLocationInfo: Support cloning of elements (to make
   mixin interstitials).
