new_etude_template: Addin to make a new etude exercise
In dtkaplan/etude: Utilities for Handling Textbook Exercises with Knitr

Creates the boilerplate for an etude exercise. Typically, this will be called by the RStudio addin, but you can also run it directly when save=TRUE

new_etude_learnr(directory = ".")

new_etude(directory = ".", learnr = FALSE)

new_etude_template(save = TRUE, exercise_id = NULL, learnr = FALSE)

`directory`	Path to the directory where the files go
`learnr`	Logical flag (default: FALSE) whether to use a learnr compatible document for the exercise.
`save`	Logical indicating whether to save the template to a new file and return the name of that file
`exercise_id`	Root name for the exercise file (.Rmd will be added). By default, a random, unique root name will be created using the `etude` naming convention, e.g., bear-walk-dish
