In seakintruth/evalCranMeta: Evaluate CRAN Meta Data

#' Install all available packages (with source) from CRAN
#' On first run this will take a long time (several hours), only installs packages not yet installed on your machine.
#' The goal is to allow us to perform in depth code reveiw of all packages on the CRAN Repository.
#' @note  
#' As of 6/26/2019 installing all on Windows, is ~19GB, 1/2 million files, and 129k folders, but setting up a mirror of CRAN is ~210GB, this is because it holds packages for all versions
