show_schema() downloads, unzips, and show in a web browser Plataforma +Brasil's
full database documentation, including its schema and other usefull information.
Docs are downloaded to a folder in the working directory.
show_schema(verbose = TRUE, browser = TRUE)
Should the function display messages and progress bar? Defaults
Should the function open a web browser to display the docs?
show_schema() is most usefull for its side effect of downloading,
when needed, and opening Plataforma +Brasil's documentation, but is also silently
returns a string containing the path to the docs' index file.
show_schema() needs an internet connection to download data in case it
does not found a cache folder with the docs from a previous request. Be aware that instability
in the Plataforma +Brasil server might produce error messagens, in which case users
should try waiting before rerunning the function.
