start_ground.bash

#! /bin/bash

# This script automatically chooses a ground station binary and config to run
# You may specify through cli arguments what config and binary should be ran
#
# Usage: ./start_ground.bash [config_path?] [binary_path?] 
#
# The search order for config files is:
#       0. CLI argument 1
#       1. ./etc/config.toml
#
# The search order for binaries to use is:
#       0. CLI argument 2
#       1. ./target/deployed/ground
#       2. ./target/release/ground
#       3. ./target/debug/ground
#
# Search orders goes from lowest to highest. With the lowest ordered path(ie: 0)
#   being searched first. Then proceeding on if the path do not exist.
