    Support for copy/paste of entities/attributes/relationships.
    This is GSoC 2008 task.

    Some of my ideas follow.
    We can implement copy-paste in two ways.

    First: the buffer is valid only within a sole project. So when you open another project, copied data is lost.
    Second, the buffer is stored in whole modeler application, or even system buffer. This allows to copy data between different projects, but is more complex because we need to create shallow copies of entities, attrs etc. Personally I use only one cayenne.xml currently.
