First version AL October 2010 Calculates local fnl and CMB lensing bispectra CMB lensing bispectra are calculated in the approximation in which the first-order result is used replacing the unlensed with the lensing power spectra This is non-perturbatively correct to about 1% Note the lensing bispectrum only includes the linear potentials, no Rees-Sciama or SZ See Lewis, Challinor & Hanson 2010 for details Note that the primordial local bispectra are unlensed (see arXiv: 0905.4732) Compile with LAPACK and -DFISHER if you want to get the fisher matrix outputs This is disabled by default in order not to require LAPACK Fisher results are with and without the cosmic variance from low L_1
