Proposal: add a Python GUI pre/post-processing tool for VPSC8

[ZhiyangNi]

We have developed a Python/Tkinter-based graphical user interface for VPSC8, mainly intended as a pre-processing and post-processing tool for the existing Fortran solver.

The current prototype provides:

• structured preview and editing of VPSC8.IN
• single-crystal .sx file preview/editing for FCC, BCC and HCP cases
• texture file preview and pole figure / inverse pole figure visualization
• structured editing of process and boundary-condition files
• Fortran-compatible run directory generation
• post-processing of common VPSC output files, including:
  • STR_STR.OUT
  • ACT_PH*.OUT
  • TEX_PH*.OUT
  • LANKFORD.OUT
  • PCYS.OUT
• no modification to the original VPSC Fortran solver

The proposed contribution would be placed under:
