v1.0.0

[1.0.0] - 2021-12-24

• Updated vector basis algorithm and reduced uncertainty when
  scaling ion drifts and electric fields for multipole fields by four orders of magnitude.
• Added support for multiple unit test magnetic fields, from dipole up to octupole.
• Added support for testing vector basis determination with a spherical Earth.
• Improved tolerance checks on vector basis during iteration so outputs better
  reflect user settings.
• Improved robustness of vector basis calculation at higher latitudes.
• Updated IGRF step method to slow integration when reaching target altitude
  to use user provided step size.
• Allow automatic expansion of field_line_trace step_size after many iterations.
• Improved robustness of apex_location_info to unreported changes in
  field_line_trace step_size.
• Added pole_tol keyword which specifies how close to vertical local
  magnetic field must be to be considered a pole.
• Added utils.datetimes_to_doubles a method to calculate year and
  fractional day of year for IGRF calls.
• Added keyword max_steps to apex_location_info
• Corrected normalization error in magnetic_vector.
• Deprecated scalar input for basis vectors.
• Reduced number of allowed recursive calls for field_line_trace
• Moved vector functions to OMMBV.vector
• Moved transformation functions to OMMBV.trans
• Moved tracing functions to OMMBV.trace
• Moved older algorithms not needed for current outputs to OMMBV.heritage
• Moved supporting Fortran functions from OMMBV.igrf13 to OMMBV.sources
• Improved robustness of apex_location_info to full_field_line tracing failures.
• Added support for GitHub Workflows
• Refactored unit testing
• Moved to setup.cfg
• Added .zenodo.json
• Improved documentation

• Validated meridional vector along maximum apex height gradient
• Retained previous basis methods, identified by heritage or integrated
• Improved accuracy and robustness of heritage techniques though new methods recommended
• Validated accuracy of scaling methods
• Incorporated IGRF13
• Expanded and organized unit tests
• Removed pysat as a dependency
• Docstring improvements

Updated Calculations
