Scala Modularisation Wiki

Given that there's no EPFL wiki that we can use, and GitHub is seen as
a good place to host code, I finally got around to uploading/wikifying
the Scala Modularisation requirements that had been discussed earlier.

http://wiki.github.com/alblue/scala/scalamodularisation

Given the work that's being done on scala-incubator, we could move
some of these wiki pages over there; but in the interim, it was easy
enough to set them up at the above location for now. This is another
fork of PaulP's scala code; the plan is to try and investigate some
module strategies against a known stable version of 2.7.x to
demonstrate the possibility, and then from there move that forwards
against a 2.8 or later build.
