 * Adds getters and setters for existing keys (and newly set() ones) to enable dot access to stored properties.
 *
 *   store.dot('foo','bar');// makes store aware of keys (could also do store.set('foo',''))
 *   store.foo = { is: true };// == store.set('foo', { is: true });
 *   console.log(store.foo.is);// logs 'true'
 * 
 * This will not create accessors that conflict with existing properties of the store object.
 *
 * Status: ALPHA - good, but ```store.foo.is=false``` won't persist while looking like it would
