Adding religion to EB

[Ferromancer]

I was thinking, now that the EB for BI installer has stabilized a bit, it would be nice for my installer to take advantage and add religions to EB.

As a list of religions of the time period I was thinking:

Celtic -- Casse, Lusotanni, Aedui, Arverni
Germanic -- Sweboz
Hellenistic -- Romani, Greek Factions, Getai? Pontos?
Semitic -- Carthage, Saba
Animist -- Saka Rauka, Saraumatae
Zoroastrian -- Seleucid? Baktria? Hai? Pahlava?
Egyptian -- Ptolomeic

I put the question marks next to ones I wasn't sure about. Somebody more familiar with the temples/gods for each faction could help me. Some factions may even have multiple religions based on which temple is installed in a region, correct (Seleucids for instance)?

To simplify things, I was wondering I could use the existing temple system. And do something like:

...temple_of_fun...
            ...
            capability
            {
                ...
                religious_belief celtic 1 { /* celtic factions */ }
                religious_belief hellenistic 1 { /* greco-roman factions */ }
            }
            ...

Though I have to admit I'm totally confused by the faction name enumerations--they don't map exactly to the modern EB factions.

Then all I would have to do, at the minimum is to add pips and this would work, right? If I don't define regions with a religion, they would just pick it up from the existing temple complex?

I think I can leave out traits and ancillaries since those are already very detailed.
