As one further step towards making LocalInterpolationRules
more like (local) functions, introduce a new method 'bind'
accepting a local finite element and a set of (local)
coefficients.  This method replaces the constructor
taking the same arguments. Instead, the local function object
now has to be default constructed.  This is just an
intermediate step, however.

Rather than a LocalFiniteElement.  This makes LocalGeodesicFEFunction
more like a dune-functions-style local function, which I think
it should be.
