# Written by retoor@molodetz.nl
# The script defines a flexible validation and field management system for models, with capabilities for setting attributes, validation, error handling, and JSON conversion. It includes classes for managing various field types with specific properties such as UUID, timestamps for creation and updates, and custom validation rules.
# This script utilizes external Python libraries such as 're' for regex operations, 'uuid' for generating unique identifiers, and 'json' for data interchange. The 'datetime' and 'timezone' modules from the Python standard library are used for date and time operations. 'OrderedDict' from 'collections' provides enhanced dictionary capabilities, and 'copy' allows deep copying of objects.
