Erase a region of the terminal. The 'start' tuple (x, y) defines the
starting position of the erase, while end (x, y) the last position.
For example if the terminal size is 4x3, start=(1, 1) and end=(1, 2)
would erase the following region:
....
.XXX
XX..

A terminal emulator within a widget.
'command' is the command to execute inside the terminal, provided as a
list of the command followed by its arguments. If 'command' is None,
the command is the current user's shell. You can also provide a callable
instead of a command, which will be executed in the subprocess.
'env' can be used to pass custom environment variables. If omitted,
os.environ is used.
'main_loop' should be provided, because the canvas state machine needs
to act on input from the PTY master device. This object must have
watch_file and remove_watch_file methods.
'escape_sequence' is the urwid key symbol which should be used to break
out of the terminal widget. If it's not specified, "ctrl a" is used.
