Namespace: UI
Introduction:
Prototype-UI is a library of user interface components based on the Prototype framework.
Its aim is to easilly improve user experience in web applications.
It also provides utilities to help developers.
Guideline:
- Prototype conventions are followed
- Everything should be unobstrusive
- All components are themable with CSS stylesheets, various themes are provided
Warning:
Prototype-UI is still under deep development, this release is targeted to developers only.
All interfaces are subjects to changes, suggestions are welcome.
DO NOT use it in production for now.

Interface: UI.Options
Mixin to handle *options* argument in initializer pattern.
TODO: find a better example than Circle that use an imaginary Point function,
this example should be used in tests too.
It assumes class defines a property called *options*, containing
default options values.
Instances hold their own *options* property after a first call to <setOptions>.
Example:
> var Circle = Class.create(UI.Options, {
>
> // default options
> options: {
> radius: 1,
> origin: Point(0, 0)
> },
>
> // common usage is to call setOptions in initializer
> initialize: function(options) {
> this.setOptions(options);
> }
> });
>
> var circle = new Circle({ origin: Point(1, 4) });
>
> circle.options
> // => { radius: 1, origin: Point(1,4) }
Accessors:
There are builtin methods to automatically write options accessors. All those
methods can take either an array of option names nor option names as arguments.
Notice that those methods won't override an accessor method if already present.
* <optionsGetter> creates getters
* <optionsSetter> creates setters
* <optionsAccessor> creates both getters and setters
Common usage is to invoke them on a class to create accessors for all instances
of this class.
Invoking those methods on a class has the same effect as invoking them on the class prototype.
See <classMethod> for more details.
Example:
> // Creates getter and setter for the "radius" options of circles
> Circle.optionsAccessor('radius');
>
> circle.setRadius(4);
> // 4
>
> circle.getRadius();
> // => 4 (circle.options.radius)
Inheritance support:
Subclasses can refine default *options* values, after a first instance call on setOptions,
*options* attribute will hold all default options values coming from the inheritance hierarchy.
