Vitor Hideyoshi 926ffc5c6b Translation of Gaussian Processes and Step Calculations Fixes
This commit temporarily uses Gaussian Heassian for step calculations, fixes fchk file reading, fixes step calculation, fixes log file and geoms formation. Also this commit adds type hinting to improve and facilitate the program development.
