Consolidating the EG a Bit

[Drashner1]

Agreed that these should be consolidated into one and that it will take a bit of modification to create a single cohesive article.

Note also that the Virch article exists in almost identical form in the Glossary. Which may be a reason to remove the article entirely, although we could also use the definitions at the start of a combined article.

So - that's one additional Editor who is approving this
