Detailed Description

we build a vspline::unary_functor which calculates the sum of gradient squared magnitudes. Note how the 'compound evaluator' we construct follows a pattern of

derive from vspline::unary_functor
keep const instances of 'inner' types
initialize these in the constructor, yielding a 'pure' functor
if the vector code is identical to the unvectorized code, implement eval() with a template
