Implement C Code Generation and Usage in Java (similar to Python)

[floxdeveloper]

Summary

Implement a feature for C code generation and its usage in Java, similar to the existing functionality available in Python.

Background

Currently, C code generation and its runtime usage are supported through the Python interface. Providing the same workflow for Java users of JCasADi would streamline high-performance computation and enable integration with Java applications.

Requirements

• Extend the code generation module to enable C code export via Java APIs.
• Implement mechanisms for compiling and invoking generated C code from Java.
• Ensure seamless loading, linking, and execution of generated code within Java environments.
• Add user and developer documentation for the new functionality (including example usage).
• Create tests demonstrating the intended workflow.

Acceptance Criteria

• Java users can generate C code from CasADi expressions.
• A documented example shows using generated C code in Java, similar to Python usage.
• Automated tests verify code generation, compilation, and usage in Java.

Additional Notes

• Reuse and adapt as much of the core code generation infrastructure as possible.
• Reference Python workflow where reasonable when documenting Java approach.
