Add optional analysis scripts

[timothyb0912]

Add optional set of { Makefile targets | script skeletons | config skeletons | source code} to the DS project representing each stage of the data science project lifecycle:

• extract,
• transform,
• load,
• draw causal graphs
• confirmatory data analysis
• exploratory data analysis
• data fine-tuning for model training,
• training,
• prediction,
• evaluate_predictions,
• simulations_statistical,
  (e.g. simulate from one's choice model)
• evaluate_simulations_stats,
• simulations_science/system/business,
  (e.g. simulate from one's parking location choice model
  + one's parking duration model
  + one's parking arrival model)
• evaluation_science/system/business,
• logging,

Consider using an optional use_default_analysis_steps feature prompt in cookiecutter for this?
