Simple terminal application which lets the user select between its input arguments and prints out the the selected choice.
The usage is simple and intuitive: use the arrow keys to move between values; press enter to select a value;
type anything to filter the values; press backspace to remove the last filter character, or delete to clear the entire filter text.
Intended to be used in shell functions and aliases, such as:
```Zsh alias goto='cd $(selector $HOME/*)'
function goto { local DIR=$(selector $HOME/*)/$1 cd $DIR ls } ```
