SSHF Mount Local Directory on Remote Cloud VPS via SSH Remote Port Forward

SSHFS_Mount_Local_to_Remote.sh

# 3.) Mount From Local to Remote
# This Gets Run on Local Raspberry Pi
# It Mounts the "Local" Source Directory to the "Remote" Destination Directory

# Local = Raspberry Pi
# Remote = Cloud VPS
# However, there is confusion
# Since we are "Reverse Port Forwarding" ,
# the "local" and "remote" terms get switched after the initial ssh command is run
# So for the "sshfs" command , whatever you get the point
