Overall, this commit is stable and produces .st data for alpha, beta, and surface deflection sweeps. This is a significant update, as now control surface deflections are now properly detected from the bd.avl command file and properly written to the AVL command file.
A lot of work was had! This is a stable release, that generates AVL .ST files for alpha, beta, AND deflection sweeps; there were issues with deflection sweeps prior to this release, so I'm really happy to have added these features. st_fileread.m scans .st output files and aero_filewrite.m takes this file and converts it to the final product
