[ANN (Toy)]: Chord Keyboard

I was watching this great video about Doug Engelbart https://www.youtube.com/watch?v=vdFejSdS9fs and got inspired to write a little chord keyboard simulator :) It's just a proof-of-concept but was fun building!

## Warning
N.B. only load this in a throwaway image because it hijacks event handling and it's easy to get into trouble

## Installing:
Gofer it
        smalltalkhubUser: 'SeanDeNigris' project: 'SeansPlayground';
        package: 'ChordKeyboard';

CkChordKeyboard uniqueInstance enable.

## Help
"These next two commented lines are to get you out of trouble:

"

## Usage
Smalltalk tools openWorkspace.

Now use your chord keyboard to type in the workspace...
Bit Key
5 a
4 s
3 d
2 f
1 space

So to type hi, type:
$s = 01000 = 8 = $h
$s + Character space = 01001 = 9 = $i
