    which is no longer maintained.
  - Moved package functionality to a Shiny application.
  - Improved code performance by updating operations to use 'Rfast'
    package methods where possible.
  - Added functionality to handle categorical covariates.
  - Increased data sizes accepted by the MetSizeR algorithm.
  - Restructured package code for readability - separated functions for
    different purposes.
  - Added a NEWS.md file to track changes to the package.
