this changes rcip to recenter exactly at a vertex, which seems safer when it comes to things like fins and axissym. open to discussion

There seems to be a bug in rcipTest where the vert passed to chnk.rcip.Rcompchunk is not the vertex obtained by interpolation.
Also, should we be subtracting off the provided vertex, rather than the interpolated end? Or should this just be for the shifted eval?

i think re-centering exactly at the vertex is the correct thing to do. we can think of the subtraction of the left end point as a sort of extra snapping done within Rcompchunk (I'm not actually sure that that step does anything, if we think about what the other matrix does to the points...)
