Task summary

Create two bash scripts which automate the launch process. One script should launch the rov and the other the deck. It would be preferred if this was not shell specific, it could run in either bash or zsh.

# Deck launch
make
source ./install/local_setup.bash # Non hard coded shell name preferred
ros2 launch seahawk deck.launch.py

# Rov launch
make
source ./install/local_setup.bash # Non hard coded shell name preferred
ros2 launch seahawk rov.launch.py
