Exa alias options + documentation

exa Enhanced v1

##
# Author:    Connor Dillon
# Created:   June 4 2020
# Some useful `exa` aliases meant to replace standard `ls` usage.
# The aliases use `l` instead of `exa` to make use of muscle memory from typing `ls` all the time :)
# Use `$ exahelp` to print documentation to console
#
# Download `exa` via:
# OSX: $ brew install exa
# Linux: $ sudo apt-get install exa
#
# Uses aliased PS1 settings, listed here for your convenience:
# Color_Off=$'\033[0m'       # Text 
# Red=$'\033[0;31m'          # Red text
# Green=$'\033[0;32m'        # Green text
# Blue=$'\033[0;34m'         # Blue text
# BIGreen=$'\033[1;92m'      # Green Bold Intense text
# Info=$'\033[0;44;97m'      # Blue background
