Function that installs and librarys as many packages as you want in one sweep

library.packages.R

# Modified from https://github.com/plynty/bls-ce-r-tools/blob/master/CE_PUMD_Wrangler.R
# Function that installs and librarys as many packages as you want in one sweep
# This action is similar to the utils::install.packages function
# just simplified/custom for my needs
# Parameters: string of package(s) name(s)
#   fOnlyEnsureInstalled if TRUE does not load packages...
# Usage: library.packages("data.table","dplyr","stringr","dtplyr")
# Returns a matrix of packages and status of install and load/attachment
