#' Attempt faster method of copying packages across libraries in the future
#'
#' Groundhog often moves packages between the groundhog library and the default personal library.
#' This is done by renaming the package folders ('renaming' the parent directory of a folder, effectively moves it).
#' This process is nearly instantaneous even for 100+ packages. The renaming method, however, is sometimes unavailable for some configurations
#' (e.g., when the groundhog and personal folders are on different drives/volumes, say external vs internal hard drives). When
#' groundhog fails to move a package by renaming it, it will produce an error, and will also make a note to permanently switch to
#' the slower method of moving packages by first coping them, and then deleting the original, which takes up to a few seconds per package, and
#' is thus much slower than renaming. If you believe the error was circumstantial and want to give
#' renaming files another chance, you may run `try.renaming.method.again()`. Future groundhog.library() calls
#' will again attempt it. If it fails again you will just get a new error message and groundhog will again switch methods.
#' It is safe to err on the side of trying again, so unless you know you are using multiple physical drives, you probably should try again, and
#' investigate a possible alternative source of the problem. To debug, you may choose `cores=1` to force sequential installation,
#' `force.install=TRUE` to reinstall possibly poorly installed dependencies, and as always, inspecting the console log as packages get installed.
#'
#'@param quiet logical, defaults to `FALSE`. When set to `TRUE` it does not display confirmation message.
