Defines abstract class IOptionManager with method(s).
Creates an interface for ATS option parsing.
It defines:
:attributes: None
:methods:
| add_operation - Adds an option to the ATS parser.
| add_version_operation - Adds version option to the ATS parser.
| parse_input_args - Processes arguments from the start.
| parse_args - Processes arguments from the start.
| register_commands - Registers a list of commands with the parser.
| parse_command - Parses the input arguments and returns an OptionNamespace.
| is_initialized - Checks if option parser component is initialized.
| __str__ - Returns the ATS option parser as string representation.
