#   Program:  set-foreground-colour-vars
#   Author:   Brian <genius@groupbcl.ca> :)
#   Date:     March 2017
#
#   Sets up environment variables to allow foreground colours to be set
#   easily in 'echo' commands.
#
#   Notes:
#   * FG_WHITE is actually a "reset to standard colours" command
#   * This file is intended to be sourced in the script that uses it
