NuPyCEE v.3.2

This updates includes:

• Code optimization, speed improvement, and path management improvement,
• Adaptation to allow OMEGA to be controlled by an external numerical integration routine,
• Improved performance and reusability of read_yields.py,
• Improved management of kwargs communication between modules,
• New plotting functions to visualize results,
• New yields_modifier parameter to alter yields value by hand.

NuPyCEE with Radioactive Isotopes

Slight optimization.
Included decay module to tread radioactivity with multiple decay channels.
Version right before merging developing branch to enable Release v4.0.

NuPyCEE in Python 3

• Switched to Python 3
• Option to decay radioactive isotopes within SYGMA and OMEGA
• Updated notebooks for the SYGMA paper

Release for SYGMA publication

Update includes:

• Minor bug fixes
• Notebooks for SYGMA paper in DOC/Papers/SYGMA_paper

Major update of NuPyCEE

Updates include:

• Neutron-star merger modeling in SYGMA and OMEGA
• Flexible data input for STELLAB
• Teaching material
• New yield tables for yield library
• Updated naming scheme for yield tables.
• Improved “extra” yields modeling

First NuPyCEE Release

This is the first official release of the NuGrid Python Chemical Evolution Environment, which contains the simple stellar population code SYGMA (Stellar Yields for Galactic Modeling Applications), the single-zone galaxy code OMEGA (One-zone Model for the Evolution of Galaxies), and the observational data plotting tool STELLAB (Stellar Abundances).
