ypp Function

function ypp(np, pid, lnstr, iinf, iind, iod, icd, ijs, instr, inf, ind, od, com_dir, js)

YPP - Post-Processing & Analysis Driver

Analyzes and post-processes results from yambo and yambo_rt calculations. Provides spectrum generation, band structure analysis, and excited-state spectroscopy including excitons, real-time dynamics, and quasi-particle databases.

Main Workflow: 1. Initialize YPP system and load ground state 2. Load response function / real-time databases 3. Execute analysis modules (RT, electrons, excitons, etc.) 4. Export formatted results and spectra
