Description
Remove:
- Menu for selecting editor mode
- EditorContainer (use a ProgramBlockEditor directly)
- TurtleGraphics
- Also remove calls to register interpreter command handlers for the turtle
- Speech recognition switch and supporting code
- MicMonitor
- Control for changing language
Remove any no-longer-needed event handlers and component state values.
Leave the unused component source files and tests in the project repo – just remove their usage from App.js.
