----------
I also think that having such a add std::vector method for display is nice - I have a 
quadratic discrete function to plot together with a flag vector on the verices. For the first
supsampling is nice for the second I get either strang results or have to interpolate
the data myself (i.e. use a lagrange type discrete function).

There is a rather crude way of solving this using corner mappings from R^d->R^(d+1) and
return the (d+1) coordinate in the P1Vector::evaluate method - it would work but is
quite a mouthful
