Dvha

* The docker compose file for DVH Analytics Docker had a bug such that it would not share import and sql connection settings between
main, admin, and settings views. A directory was created to share changes with each server.
* DVH Analytics will detect if you're using Docker and have docker applicable default sql connection settings
* Note that DVH Analytics Docker has only been validated on Mac

* If a RT Plan that is incompatible with the current version of dicom_mlc_analyzer.py, DVH Analytics would crash.
Now the command prompt will print the failed RT Plan file, and skip the MLC Analyzer tab update, preventing a crash.
* Moving to the bokeh_components directory caused relative import errors. As a temporary fix, all python files moved
to main dvh directory. This version was verified to work via pip install (and subsequently running with dvh command
calling \_\_main\_\_.py for entry point), as well as in docker.
* These versions were explicitly tested by running source code with direct bokeh serve calls, pip install of
DVH Analytics, and using docker-compose.

* Bad reference to SQL config settings in the Ignore DVH button of the ROI Name Mangaer of the Admin view

* Organize modules in tools directory
* Generalize update_all_in_db functions in database_editor.py
* ensure all options read from custom options file if available
* Backup tab functionality in Admin view was incomplete since modularization of bokeh views
* Backup selection menus now update
* Backup preferences works again

* Reorganize python files into directories:
* path updated with: import update_sys_path
* columns.py and custom_titles.py now have code wrapped in a class
* Multiple simultaneous sessions enabled again by wrapping all bokeh objects into classes
* Remove test files
* Catch keyboard interrupt in \_\_main\_\_.py for graceful shutdown
* Moved import_warning_log.txt to user's data directory
* All preferences stored in user folder now so that there's no need to run servers with sudo
* May need to copy files from <script-dir>/preferences into ~/Apps/dvh_analytics/preferences/
* Data directory defaults to ~/Apps/dvh_analytics/data but can still be customized
* All sql/preference backups stored in ~/Apps/dvh_analytics/data/backup now (can't customize)
* options.py now contains imports (os and paths.py)
* This broke load_options, code added to ignore ModuleType
* Automatically update uncategorized variations in ROI Manager after importing data, updating database, deleting data,
or reimporting database

* Move csv creation to python for less javascript (download.js)
* Some bug catches if certain fields are too long to import into its SQL column
* ROI Name Manager in the Admin view displays a table of the currently saved ROI Map of the
currently selected physician
