Grids & Folds

Add (unsafe) operations for operating on vectors.  Make it general at
first, then try to add a compile-time binding mechanism.  Is it worth
to try to start from generation directly?  Probably not.  Let's define
the datatypes first.

Added: homogeneous grids - double floats to make interoperation with
GSL easier.
