Configuration File Converter

Build a configuration file converter that reads, modifies, and saves configuration data using YAML format.

Requirements

Create a Python module that provides functionality to load configuration data from YAML format, make modifications to it, and save it back to YAML format. The module should handle hierarchical configuration structures with various data types.

Your implementation should:

1. Load configuration data from YAML strings
2. Convert the loaded data into a structured format that supports both attribute-style and dictionary-style access
3. Allow modifications to configuration values
4. Serialize the modified configuration back to YAML format

Test Cases

• Loading a YAML string with nested configuration (SYSTEM.NUM_GPUS=8, TRAIN.LEARNING_RATE=0.001) returns a structure where values can be accessed @test
• Modifying a nested configuration value and serializing back to YAML preserves the hierarchical structure @test
• Loading YAML with different data types (integers, floats, strings, tuples, lists) preserves type information @test
• Serializing an empty configuration to YAML returns valid YAML output @test
