[0.2.0] - 2019-03-31

Added

• Added download_all_data() function to Universe module to allow user to update
  package data at runtime.
• Added solar flux and geomagnetic index data classes to Universe module.
• Added EarthEnvironment sub-package to store Earth-specific models and functionality
• Added SpaceWeather to EarthEnvironment module to store data releated to space weather and geomagnetic activity.
• Added NRLMSISE00 module to EarthEnvironment package to implement higher-fidelity atmospheric density simulation.
• Added Integrators module to implement internal numerical integraiton in a
  manner which makes future improvements more easily accomplished.
• Added Propagators module to provide better dynamics integration tools.

Changed

• Moved orbit dyanmics function deriv_orbit_earth out of OrbitDynamics module and into Propagators module. Also renamed function to fderiv_earth_orbit

Removed

• Remove base Simulation module and associated funcitons including propagate_orbit

Fixed

• Fixed scripts and functions used to download package data
• Fixed how many functions were specifying types and default arguments. There were
  a number of instances of ineffectual type specification.
• Lots of documentation improvements and fixes.

Initial Release

Changelog - [v0.1.0]

Initial release of the SatelliteDynamics.jl package.

The purpose of the package is to provide a high-fidelity satellite dynamic modeling toolbox with an easy-to-use API. The goal is to make it easy for enthusiasts, researchers, and satellite operators to build upon the modules provided herein without compromising accuracy or performance.

The initial release provides a tested toolbox for modeling the dynamics of Earth orbiting satellite, management of Earth reference frames, and converting between satellite attitude representations.
