[admin] computed-class

[Levente Mészáros]

Hi,

I would like to make the computed-class subproject from cl-wdim a
separate project, because I believe it might be useful for some other
projects too and it's quite independent from the rest of cl-wdim.

I already have an account and my user name is lmeszaros.

The project provides a class meta object called computed-class which
can be used to define classes which support per instance lazily
computed slot values.

The license is BSD.
