META-CAPABILITY: meta_unnamed
Code that creates code!

"""
This capability provides a template engine that can generate Python capabilities programmatically. It allows users to create new capabilities by specifying a template and parameters.

The TemplateEngine class handles generating Python code from templates, saving it to specified files. The baseCapability class is extended by all generated capabilities.

Features:
- Load multiple template directories
- Generate capability classes from templates
- Save generated code to files
- Extensible and customizable template structure

Example Usage:
>>> engine = TemplateEngine()
>>> engine.add_template_dir('templates/')
>>> engine.generate_capability(
...     name='greeting',
...     description='Capability that generates greetings.',
...     author='John Doe'
... )
'Successfully generated capability: greeting.py'
