Potentially unused functions

[elazarg]

Using uncalled I got a list of functions that are apparently unused. Listed below are those I couldn't convince myself they are actually needed:

• [ ] globalmaptiles.py: LatLonToPixels, PixelsToRaster, ZoomForPixelSize
• [ ] graphqlSchema.py: resolve_accident_markers_hebrew
• [ ] infographics_utils.py: convert_roads_fatal_accidents_to_frontend_view
• [ ] infographics_utils.py: get_widget_factories
• [ ] infographics_utils.py: sum_road_accidents_by_specific_type
• [ ] models.py: get_segment_id
• [ ] pymapcluster.py: get_cluster_size
• [ ] utilities.py: row_to_dict
• [ ] vehicle_type.py: to_type_code
• [ ] vehicle_type.py: get_categories
• [ ] parsers/cbs/executor.py: delete_invalid_entries
• [ ] parsers/infographics_data_cache_updater.py: get_infographics_data_from_cache
• [ ] parsers/infographics_data_cache_updater.py: get_infographics_data_from_cache_by_road_segment
• [ ] parsers/location_extraction.py: reverse_geocode_extract
• [ ] parsers/news_flash_db_adapter.py: recreate_table_for_location_extraction
• [ ] parsers/twitter.py: extract_accident_time
• [ ] widgets/widget.py: get_name, get_rank (look like simple getters, which are unneeded in Python)
• [ ] widgets/widget.py: get_widget_files

Any of those may be actually needed of course. I think it's worth annotating those cases explicitly in the code.

A similar tool, vulture lists many additional functions and variables, though it also has many false positives.
