What are eggs?

[Dov Grobgeld <dov grobgeld gmail com>]

While trying to make a up a family for a new widget, I got reminded of seeing the term "egg" over the years in relation to gtk, but I never really understood what it means, who came up with the concept, and how it is "supposed" to be used?

My guess is that it is related to real eggs that are abiding their time to hatch, and in the same way experimental concepts are abiding their time? Is that it?

Thanks!
