This pull request introduces several key updates and improvements to the Polypheny JDBC Driver:

  1. Graph Results Support: Added support for handling graph results, including edges and nodes.
  2. Skeleton Code for Paths: Implemented seleton code with todos and not ipmlemented exceptions for path support, pending server-side fix (workin int he interface but not polypheny itself).
  3. Bug Fixes: Addressed issues with broken unit tests and fixed bugs related to time and date conversions.
  4. Standard Compliance Adjustments:
    • Added deprecated annotations to getters as per JDBC 4.3 standards.
    • Introduced an asString method utilized by toString in result sets.
    • Added exceptions for illegal conversions and unimplemented features, particularly paths.
  5. Multi-Model Extension Features: Enhanced support for multi-model queries (batching, named/indexe dparameters, prepared statements...).
  6. Code Cleanup:
    • Removed unnecessary static imports.
    • Improved variable name clarity.
    • Eliminated printouts from tests.
