Starmatrix - Version 1.3.0

1.3.0 (2020-12-10)

SuperNova rates are now computed accounting for the total number of stars created per unit of stellar mass
Added new DTD option: Greggio, L. 2005
Added dataset of solar abundances from Lodders et al. 2019
Added two_steps_t option for integration_step setting: The integration will use two time steps: [half the lifetime of a 100 solar masses star for the given metallicity] as time step for stars bigger than 4 solar masses, and 100 times that for less massive stars. If this option is selected the total_time_steps setting is ignored
Added fixed_n_steps option for integration_step setting: The integration will take exactly the number of time steps specified in the next two settings (integration_steps_stars_smaller_than_4Msun and integration_steps_stars_bigger_than_4Msun)
Removed DTD from Mannucci, Della Valle, Panagia (2006) (was deprecated in v1.2.0)
