Classes
 ClassDescription
 BitBoardUtil BitBoardUtil.as class.
 BitField BitField.as class.
 Enum AS3 Fake Enum class
 FilterUtil FilterUtil.as class.
 LogUtil Use a simple utility method to retrieve the logger for a particular class, instead of passing in the qualified class name as a string.
 MathUtil Permutation Utility class version 1.
 MixinUtil That title may be a bit of a stretch, AS3 does not support mixins in the same way as Ruby, but it is possible to define a set of methods and/or attributes in a single file and then mix those methods and attributes into your AS3 classes.
 ProxyArray ProxyArray.as class with num/obj sum and clear dynamic functions support.
 SingletonFactory One of the problems with the Singleton design pattern (there are many) is that it encapsulates the single instance nature of the pattern within the class, when very often the requirement for only one instance is not a feature of the class but a feature of the application that is using the class.
 SortUtil SortUtil.as class.
 VersionController This class providing auto update version number functions which displayed in the flash player context menu.
