[FLASH-BUGS] Bug in quadratic_cartesian interpolation scheme?

[Mike Zingale]

yes, I added the fixed to the cylindrical and spherical prolongation
routines that I wrote -- I did not get around to the cartesian ones yet,
mainly because that would break a lot of the test suite, and I didn't want
to deal with that at the time.
