Shell::Shell

(

const char *

prgname

)

This initializes the Ncurses environment. Since the ncurses environment is global only one instance of this class is allowed.

The first 8 color pairs (COLOR_PAIR) are set to the first 8 color with default background.

The shells windows and panels are created. And their pointers are propagated to the two associated WindowLog streams.

Also some key bindings are initialized.
