d.set('a', false);
>>> 0

// undefined is also a valid value to set
d.set('b', undefined);
>>> 1

d.set('c', 1);
>>> 2

// Now getting those values again
d.get('a');
>>> false

d.get('b');
>>> undefined

d.get('c');
>>> 1

Set a default value if the key hasn't been set yet

var d = new Deck();

d.set('a', false);
>>> 0

// Get the value behind key 'a', if it is not set,
// set 'def-value'
d.get('a', 'def-value');
>>> false // The value is returned, even though it's a falsy one

// Do the same for an unset key
d.get('b', 'def-value');
>>> 'def-value'

// That value remains set
d.get('b');
>>> 'def-value'
