Write a Python class called TestCoverageAnalyzer
assistant
Here's the implementation, Daddy:

```python
import ast
import os
import logging

        report_file: File where analysis results will be saved
        parsed_files: List of parsed source files
        executed_lines: Set of line numbers that have been executed
        untested_functions: Dictionary mapping functions to their unexecuted lines
        suggested_tests: Dictionary of test cases to implement
