Update install and use instructions

[smathermather]

# Parent:

sudo apt update && sudo apt upgrade -y && sudo apt dist-upgrade -y && sudo apt autoremove -y && sudo reboot
sudo apt install git
git clone https://github.com/opendronemap/odm360 --depth 1
cd odm360/
./parent_pi_setup.sh 
python3 -m flask run --host=0.0.0.0

# Child:

sudo apt update && sudo apt upgrade -y && sudo apt autoremove -y && sudo apt dist-upgrade -y && sudo reboot
sudo apt install git
git clone https://github.com/opendronemap/odm360 --depth 1
cd odm360
provisioning/child_pi_setup.sh 
cd provisioning
./database_setup_child.sh
python3 -m odm360

Parent is now running:

Now, to more fundamental questions: how do I turn the child on?

Will update the above shortly, but changed the install process for child pis to simplify:

Suggestions ToC:

1. Hardware assemblage (subsections on parts, 3D printing, wiring and putting everything together).
2. Installation (short install for .deb users, longer install for developers)
3. how to use: instructions on front end (subsections general explanation 1) make a new project; 2) change settings; 3) Survey; 4) file management; 5) status)

Chapter 1 is on Steve and Ivan, chapter 2 on Schuyler and Ivan; Chapter 3 on Hessel and Iddy
