Moved util functions ("reverseSortBy", "center" and "interpretdate") from "tiki/tools" to "tiki/util".
Added two new controlmodels: IntModel and FloatModel
Removed the method "getFormattedValue", implemented by some control models. This is now handled by the associated control views.
Bug fix in Traits.Model - Trait.name was not set
Improved debugging/introspection: Added new util Util.extend adding support for named constructors. All traits and controlmodels are now named and implement toString.
Tools.Selectable is now data driven
Many traits now throw exceptions on type and value errors.
