Add static/compile time sizing to EuclideanManifold

Browse Source 
This brings it in line with other manifolds like SphereManifold
and LineManifold, where the user has the choice to specify the size
of the manifold at compile time or runtime.

Most of the time the size is known at compile time so this will
speed up the common case.
