Initial import of new Einstein stuff. This has the new thorns, but not all

are fully functional yet.  

When I have completed this stage I'll send an updated spec out with some 
questions which have arisen during this process.

Please don't import anything new without checking with me first, as I want 
to play games on the server copying cvs files around to preserve histories 
on files which are only minimally touched.

+Cactus Code Thorn StaticConformal
+Authors    : Tom Goodale
+CVS info   : $Header$
+--------------------------------------------------------------------------
+
+Purpose of the thorn:
+
+This thorn provides the variables defining a static conformal factor
+which is used to transform the physical metric.  If this thorn is
+active and the ADMBase::metric_type parameter is set to
+`static conformal' then the ADMBase::g... variables are the
+conformal values as opposed to the physical values.
+
+The transformation is
+
+$$ g_{ij}^{\mbox{physical}} = \psi^4 g_{ij}^{\mbox{conformal}} $$
+
+The extrinsic curvature is not transformed.
