RAII core idea for exception safety

Options

- 2Acquire all resources in main before any use, then release them explicitly at the end of main
- 3Use raw new and delete carefully with manual try/catch blocks around every allocation site
- 4Initialize all resources at program startup in a fixed order and free them at program exit
