- haromnzation_abstract_one folder to save and make reproducible work for brain mapping abstract
- exact freeze of environment in precise_working_environment
- harmony module for functions related to implementing common harmonization algorithms
- harmony also includes new graphing functions in harmony module to illustrate harmonization effects e.g.
`compare_harm_one_site_violins` and `compare_harm_multi_site_violins`
- updates to seperated module including:
- new functons in seperated to bin data on a continous variable
- generalized functions for k-folding as specific to project in seperated module
- k folding which allows splitting on twp variables (one continous, one categorical) with
`stratified_cat_and_cont_categories_shuffle_split` function
- command-line sex recoding over a folder
- command-line loging of columns over a folder
