PAOFLOW.gen.aflow_qe

Backward-compatible entry point for the QE-input generator.

The implementation now lives in PAOFLOW.gen.qe_input, which supports multiple materials databases (AFLOW, C2DB, …). This module is preserved so that the paoflow-gen-qe console script and any existing imports keep working; main defaults to --source auto so historical AFLOW invocations behave exactly as before.
