+/**
+* Creates a new class (constructor function) which extends the base class passed in as the second argument,
+* and mixes in the array of extensions provided.
+*
+* Prototype properties or methods can be added to the new class, using the px argument (similar to Y.extend).
+*
+* Static properties or methods can be added to the new class, using the sx argument (similar to Y.extend).
+*
+* **NOTE FOR COMPONENT DEVELOPERS**: Both the `base` class, and `extensions` can define static a `_buildCfg`
+* property, which acts as class creation meta-data, and drives how special static properties from the base
+* class, or extensions should be copied, aggregated or (custom) mixed into the newly created class.
+*
+* The `_buildCfg` property is a hash with 3 supported properties: `statics`, `aggregates` and `custom`, e.g:
+*
+*     // If the Base/Main class is the thing introducing the property:
+*
+*     MyBaseClass._buildCfg = {
+*
+*        // Static properties/methods to copy (Alias) to the built class.
+*        statics: ["CopyThisMethod", "CopyThisProperty"],
+*
+*        // Static props to aggregate onto the built class.
+*        aggregates: ["AggregateThisProperty"],
+*
+*        // Static properties which need custom handling (e.g. deep merge etc.)
+*        custom: {
+*           "CustomProperty" : function(property, Receiver, Supplier) {
+*              ...
+*              var triggers = Receiver.CustomProperty.triggers;
+*              Receiver.CustomProperty.triggers = triggers.concat(Supplier.CustomProperty.triggers);
+*              ...
+*           }
+*        }
+*     };
+*
+*     MyBaseClass.CopyThisMethod = function() {...};
+*     MyBaseClass.CopyThisProperty = "foo";
+*     MyBaseClass.AggregateThisProperty = {...};
+*     MyBaseClass.CustomProperty = {
+*        triggers: [...]
+*     }
+*
+*     // Or, if the Extension is the thing introducing the property:
+*
+*     MyExtension._buildCfg = {
+*         statics : ...
+*         aggregates : ...
+*         custom : ...
+*     }
+*
+* This way, when users pass your base or extension class to `Y.Base.create` or `Y.Base.mix`, they don't need to
+* know which properties need special handling. `Y.Base` has a buildCfg which defines `ATTRS` for custom mix handling
+* (to protect the static config objects), and `Y.Widget` has a buildCfg which specifies `HTML_PARSER` for
+* straight up aggregation.
+*
+* @method create
+* @static
+* @param {String} name The name of the newly created class. Used to define the NAME property for the new class.
+* @param {Function} main The base class which the new class should extend.
+* This class needs to be Base or a class derived from base (e.g. Widget).
+* @param {Function[]} extensions The list of extensions which will be mixed into the built class.
+* @param {Object} px The set of prototype properties/methods to add to the built class.
+* @param {Object} sx The set of static properties/methods to add to the built class.
+* @return {Function} The newly created class.
