proposed V8 changes

[ramosaj]

• Populate code for all tables
• some nomenclature changes
• Trial indices are now sequential and consistent, representing the convention:
  • end frame f0 indicates trial ended closer to f1 than f0 (rounded frame -1)
  • start frame of f1 indicates trial started closer to f1 (rounded frame)

[ramosaj]

• Need to add Docstrings to all the functions in func.py
• Make note about 4-9
