MUSIC v3.0 release note

This release is built upon the previous public release at https://sourceforge.net/projects/music-hydro/.

MUSIC v3.0 implements many new features and improves numerical performance.

Major new features:

• Implement a dynamical initialization scheme with source terms for RHIC Beam Energy Scan simulations https://arxiv.org/pdf/1710.00881.pdf
• Implement the evolution of baryon diffusion current in 3D simulations https://arxiv.org/pdf/1804.10557.pdf
• Incorporate a QCD Equation of State at finite densities https://arxiv.org/pdf/1902.05095.pdf
• Interface with the JETSCAPE framework https://arxiv.org/pdf/1903.07706.pdf

Numerical Improvements:

• Memory requirement is reduced by a factor of 30 over previous versions 💪
• Numerical performance is improved by a factor of 3 over previous versions
• Parallelization is implemented in all 3 dimensions using openMP instead of MPI
• C++11 standard is introduced
• Many unit tests and integration tests are implemented
• Adopt emojis in the program message output 👍
