Progress for 10-5-17

There is a button class that handles some collision detection (no reaction) and all its graphics details. With support inside main, it can be moved (right now only the grid button is supported). The only buttons there that works is the grid button. There are display lists for 16 1-point components and 5 2-point components, all shown in the screenshot. The circuit shown is the same as before; hardcoded using the single-point component class. That class has no provisions for interacting with the user. Those will probably be handled in main in a general fashion. Should probably add a standard cursor button to switch back from deleting. Next up:

• Make those buttons interact with each other.
• Make it possible to add components using the buttons.
• Make it possible to edit components.
• Create a button configuration file.
• Screenshot support with provisions for existing files.
• Schematic file format.
• No windows API here. It will load and save from hardcoded filenames.
