  Log:
  the last commit of this file accidently checked in something I was trying.
  
  because it is faster, use conj instead of invert in xform(quat,vec) and
  operator*(quat,vec).  I've run tests, and using conj or invert both yield
  the same results (cool), so use the faster one.
  
  somehow I didn't trust my previous commit where I said to use conj,
  but I've retested it, and I was right.  Now there is a test in the
  test suite for it (to do the raw calculation of quat*vec using conj or
  invert comparing if they equal, which they should.)
