Currently they are the default from quadpack (epsrel=1e-8 and
lim=200). My preference for optional arguments is nintegrate(expr,
var, lo, hi, epsrel=1e-8, lim=200) and not that the meaning of an
optional argument is defined by position (epsrel the fifth argument
and lim the sixth like in quadpack). I can add this.
