This is an implementation of introducing window management to Emacs. * Management of list of editable buffers * Assignment of windows for pop-up buffers * Switching window layout like the perspective in eclipse * Plug-in extension

The current implementation has following perspectives: * code : main coding layout * two : side by side layout * doc : reading documentation layout * dashboard : showing plug-ins like dashboard in Mac OSX * array : selecting buffers like expose in Mac OSX
