Description: The Traits project is at the center of all Enthought Tool Suite development
        and has changed the mental model used at Enthought for programming in the
        already extremely efficient Python programming language. We encourage everyone
        to join us in enjoying the productivity gains from using such a powerful
        approach.
        
        The Traits project allows Python programmers to use a special kind of type
        definition called a *trait*, which gives object attributes some additional
        characteristics:
        
        - **Initialization**: A trait has a *default value*, which is
          automatically set as the initial value of an attribute before its
          first use in a program.
        - **Validation**: A trait attribute's type is *explicitly declared*. The
          type is evident in the code, and only values that meet a
          programmer-specified set of criteria (i.e., the trait definition) can
          be assigned to that attribute.
        - **Delegation**: The value of a trait attribute can be contained either
          in the defining object or in another object *delegated* to by the
          trait.
        - **Notification**: Setting the value of a trait attribute can *notify*
          other parts of the program that the value has changed.
        - **Visualization**: User interfaces that allow a user to *interactively
          modify* the value of a trait attribute can be automatically
          constructed using the trait's definition. (This feature requires that
          a supported GUI toolkit be installed. If this feature is not used, the
          Traits project does not otherwise require GUI support.)
        
        A class can freely mix trait-based attributes with normal Python attributes,
        or can opt to allow the use of only a fixed or open set of trait attributes
        within the class. Trait attributes defined by a classs are automatically
        inherited by any subclass derived from the class.
        
        Prerequisites
        -------------
        You must have the following libraries installed before building or installing
        Traits:
        
        * `Numpy <http://pypi.python.org/pypi/numpy/1.1.1>`_ to support the trait types
          for arrays. Version 1.1.0 or later is preferred. Version 1.0.4 will work, but
          some tests may fail.
        * `setuptools <http://pypi.python.org/pypi/setuptools/0.6c8>`_
