descendents()

List all descedents of this class. 

  class X ; end
  class A < X; end
  class B < X; end
  X.descendents  #=> [A,B]

NOTE: This is a intesive operation. Do not expect it to be super fast.

This method is also aliased as subclasses

# File lib/facets/class/descendents.rb, line 13
  def descendents
    subclass = []
    ObjectSpace.each_object( Class ) do |c|
      if c.ancestors.include?( self ) and self != c
        subclass << c
      end
    end
    return subclass
  end
prepend( aspect )

Prepend an "aspect module" to a class. 

  class Firetruck
    def put_out_fire(option)
      "Put out #{option}"
    end
  end

  module FastFiretruck
    def put_out_fire(option)
      super("very #{option}!")
    end
  end

  Firetruck.prepend(FastFiretruck)

  ft = Firetruck.new
  ft.put_out_fire('fast') #=> "Put out very fast!"

Implementation of this method has some limitations, in that it works by overriding new and allocate.

CREDIT Trans

TODO: Perhaps rename this to preallocate, b/c of 

      the way it works. It is not really a clean
      prepend, like that of Module#prepend.
