• get_assoc() - add return_all_terms argument. Default is false. If TRUE, adds a new col terms and returns the estimates for all independent variables in the models.
• get_assoc() - remove subset_d argument
• get_assoc() - fixed if exposure or outcome needs to be protected by backticks (previously failed if variable was something like "bmi-1")
• get_assoc() - fixed problem where covariate estimates were also included in certain situations (e.g., if x="age" do not get covariate "percentage")
• Update examples for many functions
