#----- 1. create the report directory ------------------------

#----- 2. generate Rmd files with Rmd templates --------------
#   a. templates without placeholder variables:
#         copy templates from tool directory to the working directory.
#   b. templates with placeholder variables:
#         substitute variables with user input values and place them in the working directory.
