Fix typo in usage string
Update pixelImage so that map is only applied to data within range, rescaled to 0-1.
Fix (width,height) swaps
Update usage strings to clarify that z-dependent Omegas are relative to present-day critical density.
Add growthFunction to evaluate G(z) using the approx. eqn (16) of Weinberg 2012.
Start work on a Gaussian random field generator (not debugged yet).
Add growthVarianceFunction for calculating k(NL) from Weinberg 2012 eqn (37).
Add logGrowthRate function and use it in growthFunction
Add NnuMassive option to createCosmology which defaults to 1 (a la Planck)
Add Omega_nu(z) function and use it and NnuMassive in exportToCamb.
Add checks on NnuMassive and mnu.
Omega(rad) only includes massless neutrino contribution and Omega(matter) is assumed to include any massive neutrinos.
Add the nifty new createCMBVariant function, which reproduces Table 1 of Weinberg 2013.
Update usage string for recombinationXe (no longer returning matter temperature)
Document type = Photon/Baryon option
Add method = NIntegrate / NDSolve option to internal buildFunction (does not do anything yet)
Implement alternative NDSolve method for internal buildFunction (NIntegrate is still the default)
Make NDSolve the default method for buildFunction and increase default pointsPerDecade from 50 to 200 for opticalDepthFunction
Do not plot buildFunction integrand by default
Limit automatic step size in buildFunction integration
