[oe] SCM scorecards

[Graeme Gregory]

Moving a private discussion public I started to add a quick score card for SCM's

This is currently how I see feature support.

So far we seem to have this list where goodness is 1-5 (5 being good)

CPU Load Git 5 Monotone 3
Ease of branching Git 5 Monotone 5
Ease of Branch Merging Git 4 Monotone 3
Ease of Serving Git 1 Monotone 5
Ease of Distributed SCM Git 2 Monotone 5


Im sure there is more scores we can add to this list. And you might not 
agree with my scores, but it seems pretty close so far.
