reads lines from stdin, lets user choose one line in an urwid (ncurses like)
interface, then prints that line to stdout and exits. Input will be aligned to

get_data.sh | choose | other_script.sh
Choose should run on all *NIXes, but might not work in non utf-8 locales.
An example of piping the output of pc_query -t searchstring into choose:
