Installed() - runs when driver is installed, via pair or virtual
configure() -runs when driver is installed, after installed is run. if capability Configuration exists, a Configure command is added to the ui
initialize() - runs first time driver loads, ie system startup when capability Initialize exists, a Initialize command is added to the ui.
updated() - runs when save is clicked in the preferences section
Initialized() is not a capability or built in driver command, it's a local method only, I've never understood it either, i guess it saves a few lines of duplicate calls...
